Introduction This document provides information about the S6700 Multi Protocol Transceiver IC. It describes the integrated circuit and how to implement it. 1.2 System Description The HF Reader System Series 6000 works at a frequency of 13.56 MHz. It comprises a reader, antenna and transponder (for example: smart label) and is used for wire-
less identification. The system works according the reader talks first principle which means that the transponder keeps quiet until the reader sends a request to it. The reader can rapidly and simultaneously identify numerous transponders in the antennas field. It can write data to and read data from the transponders; either in addressed mode by using the factory programmed read only number, or in general mode to all of the transpond-
ers in its field. The read/write capability of the transponder allows users to update the data stored in the transponders memory anywhere along its movements. 1.3 Product Description The S6700 Multi Protocol Transceiver IC opens a rapid path for the development of a broad range of 13.56 MHz RFID readers. It provides the receive/transmit functions required to communicate with a variety of transponders that operate in the 13.56 MHz ISM band. A transmit encoder converts the transmitted data stream into the se-
lected protocol; protocol selection is done in the header of the transmitted data string. The transmitter can provide up to 200 mW of RF power to a matched 50 load with a 5 V power supply. Higher output power can be obtained by an external amplifier. The receive decoder converts the signals from the RF receiver into a simple data string. The digital interface provides on-chip data encoding and recovery, thereby minimiz-
ing the software design efforts for the end user. Communication with the circuit is achieved by means of a three wire serial link. Figure 1: S6700 Multi Protocol Transceiver IC (RI-R6C-001A) 1.4 Communications Protocols The Transceiver IC can handle different RF protocols as follows:
1. Tag-it protocol. 2. 3. 4. Direct mode where data can be passed directly thru to a transponder; using the ISO / IEC 15693-2 [2]. ISO / IEC 14443-2 (Type A). correct modulation, timing, and command structure. 7 S6700 Multi-Protocol Transceiver IC - Reference Guide June 02 1.5 Delivery The Transceiver IC is available in an SSOP20 plastic package and will be delivered in quantities of 1500 units packed tape-on-reel.

Figure 4: Simplified Block Diagram RX input Rectifier 423/484/848 kHz Modulation dept / out Return loss better 20dB Vcc Gnd Lowpass Filter Linear PA Receive Decoder M_ERR Mode Register Transmitt Decoder Oscillator 13.56MHz Dout Din SCLOCK 2.1.1 Power Supply The Transceiver IC requires a nominal 5 volts external power supply. Operation is guaranteed between 3 Volts and 5.5 Volts. The current drain depends on the anten-
na impedance and the output matching network configuration. We strongly recom-
mended that you use a well regulated supply as power supply ripple and noise will severely degrade the overall system performance. 2.1.2 Transmitter The output transistor is a low Ron MOSFET. The drain is directly accessible on the TX_OUT pin. A recommended application schematic optimized to drive a resistive fifty ohms antenna with a five volts power supply is shown in Appendix A. A simple resonant circuit or/and a simple matching network can be connected to the output to reduce harmonic suppression and enhance the general performance. 100% modulation is achieved by means of gating the square wave drive of the output transistor. 10 June 02 Chapter 2. Transceiver IC Description 2.1.3 Receiver The ten percent modulation depth is obtained by means of switching a resistor in se-
ries with the output transistor source connection. Increasing the value of this resistor further increases the modulation depth. The transmit encoder converts the data into the selected RF Protocol to be trans-
ferred. The communications speed varies from 5 to 120 kbaud and must be at least the speed of the selected transponder protocol. An input buffer is implemented in or-
der to have a sufficient number of bits available for the RF transmission. The receiver input is typically connected to the antenna through an external resistor. The modulation from the tag is then recovered by means of a diode envelope detec-
tor. The receiver decoder issues the received data directly to the controller in binary data format. The communication speed and RF protocol is defined by the selected mode. Start, stop and errors in the received data string are detected and indicated at the output. 2.1.4 Reference Clock and Internal Oscillator The reference clock can be obtained externally by applying a suitable clock signal to the XTAL2 pin. A sine wave centered at VCC/2 or a CMOS logic compatible signal is an acceptable external system clock. The built-in reference oscillator will work ei-
ther with a quartz crystal or a ceramic resonator. The nominal system clock frequen-
cy is 13.56 MHz, but the oscillator will work at any frequency from 4 MHz to 16 MHz. A buffered version of the crystal oscillator signal is available for synchronization pur-
poses on pin 8 (XTAL_CLOCK). 2.1.5 Reset Defaults and Power Management After a power on reset has been performed, the device is placed in its default config-
uration. There are three available power modes. In the first mode, the device is fully powered. In the idle mode, only the reference oscillator and a minimal set of associ-
ated circuitry are running. In the power down mode, the device internal bias system is completely switched off. The circuit is woken by applying a rising edge on the DIN line while SCLOCK is held high. 2.1.6 Serial communication interface The communication interface normally uses three wires:
SCLOCK, serial clock, bi-directional. DIN, data input, as seen by the circuit DOUT, data output, as seen by the circuit The commands are sent with the most significant bit (MSB) in the first position. All signals are internally synchronized with the system clock. The bit protocol is fully described in Chapter 4. 11 S6700 Multi-Protocol Transceiver IC - Reference Guide June 02 2.2 Pin Description Figure 5 shows the Transceiver IC and the signals on each pin.

1) 2) 3) 4) This parameter is specified with the IC wired as shown in the typical application circuit shown in Appendix A, with the trans-
mitter switched on. The external clock symmetry is of paramount importance. It has a direct influence on the transmitter output power. When using a sine wave as an external clock input, it must not show visible distortion. If a square wave is used, its duty cycle has to be equal to 50%. In all cases, the resulting duty cycle should be checked on the XTAL_CLK pin when it is configured as an out-
put. The maximum ripple current could result in a 10% reduction of the reading distance. The minimum frequency must be high enough that the Trans-
ceiver IC always has data available to send. Figure 6: Transceiver IC Sending Data Sclock DOUT T1 T1: typical 300ns 16 June 02 Chapter 3.

All signals trav-
elling on this interface must be resynchronised and debounced. It is important to al-
low a 70 ns debounce time before looking for any signal change. For example, if SCLOCK rises 70 ns before DIN the Transceiver IC serial interface may see them as rising together. For each communication, the remote controller must send a command to perform an appropriate sequence. A typical command is structured as follows: (S1, eight bits command, data, ES1). More actions may follow a specific command but sending S1 will in general initiate a new sequence. A sequence is defined as being all signals between the first S1 (that belongs to the sequence) and the next S1 (that belongs to the next sequence). Size/length S1 Command Bin. Data ES1 Start Command byte Binary data Stop 1 Bit 8 Bits X Bits 1 Bit depending on message Figure 8: Command Structure Start Command S1 CMD bit 7 bit 0 Bin. Data B-Data Stop ES1 Note:
You should switch the transmitter on (as described in section 4.1.4) before you send the first command, otherwise it could happen that the first command is not correctly performed. 4.1.1 Definition of Start (S1), Stop (ES1) and Data bit Start, stop, and data are indicated by the sequences:
- Start (S1) is defined as the start of the communication sequence between the Transceiver IC and the micro-controller. It is a low-to-high transition on the DIN line while SCLOCK is held high.
- Stop (ES1) is defined as the end of the communication sequence and is a high-to-low transition on the DIN line while SCLOCK is held high.
- Each data bit is latched by the rising edge of SCLOCK. The value of the data bit must be settled and has to remain the same while SCLOCK is high.

An overview of supported Command Bytes is given in Appendix B. 4.1.3 Transmitter Off Command Figure 10 shows a special and fast command to shut down the carrier. This can be constructed with an S1 sequence followed by an ES1 sequence. Therefore, this has been written S1 and ES1 in the symbolic representation. The transmitter is kept ON after a RF command was initiated. To switch the trans-
mitter OFF the following sequence is used:
- A transition of SCLOCK from low -to-high.
- A low -to-high transition followed by a high-to-low transition on the Din line while SCLOCK is held high the whole time.
- A transition of SCLOCK from high to low. Figure 10: Shut Down Command TX OFF Symbolic S1 ES1 Sclock Din Dout The width of the pulse of Din must be at least 1.2 s in order to secure the system, and avoid any confusion between a TXOFF command and an S1 command, in case any spurious spike(s) are present on the serial link. It is not necessary to switch off the transmitter before sending another command and data stream to the Transceiver IC. 4.1.4 Transmitter On command The transmitter can be switched on with each of the RF commands in Table 5 except for the configuration commands. The fastest command to switch the transmitter on is a register mode command without data, using the sequence: S1, 1, ES1. 22 June 02 Chapter 4. Protocol Definition 4.2 Operating Modes There are two operating modes available: normal mode and register mode. 4.2.1 Common Points (Normal and Register Mode) Following the S1 bit and the command (either normal or register mode), the rest of the sequence is the same. The number of data bits is arbitrary. The controller sends ES1 when all data bits have been sent. It is the responsibility of the controller to check that the number of data bits is consistent. For example, sending 7 data bits in mode 1out 256 is not consist-
ent. The controller will have no feedback on this error, wrong data or no data at all could be sent. The various CRC sent by the TAG should allow the controller to un-
derstand its mistake and, if necessary, to reinitiate a sequence. The first bit ES1 will probably not finish the sequence since an answer from the TAG will probably be expected. This is explained in figures 12, 14 and 15. Note that S1 starts the sequence but does not physically modulate the carrier with a SOF. The SOF will be generated by the Transceiver IC itself before sending data. This SOF may depend on the mode. It may only be sent after several data bits have been received by the Transceiver IC. For example, the SOF may be modulated only when 8 bits have been received in the mode 1 out 256. This behaviour is similar in the mode 1 out of 4. 4.2.2 Normal Mode Figure 11 represents the Normal Mode. The user sends some configuration inside the command (definition see Table 5) and starts sending data that will be transmitted by the way of modulating the carrier. SOF, data, EOF will be sent to the TAG. There is no timing correlation between the data in the serial interface and the timing of the data transmitted to the TAG. This is the reason why a buffer (FIFO) has been imple-
mented in the Transceiver IC. The signals related to the FIFO will be described in FIFO management section 4.5.2. Figure 11: Normal Mode Normal Mode Symbolic S1 command= normal mode data= to be sent to TAG ES1 b7 b0 Sclock Din Dout Example:

Stop (ES1) 4.2.3 Register Mode Figure 12 represents the Register Mode command. This command is only one bit long and not 8 bits long like all other commands. In Register Mode, the configuration used is the one that has been previously pro-
grammed in the Transceiver IC. This configuration should be written using Write to Configuration Register (Figure 14) during a previous communication with the Trans-
ceiver IC. The Configuration Register definition is shown in Appendix C. Figure 12: Register Mode Register mode Symbolic S1 cmd b7 data= to be sent to TAG ES1 Sclock Din Dout Example:

Arbitrary length binary data stream. The bits are en-
coded according to the protocol format defined in the RF protocol registers 1 Bit 24 June 02 Chapter 4. Protocol Definition 4.3 4.3.1 RF Protocol General A description of the RF Protocol according to ISO 15693 and ISO 14443 can be found in the relevant ISO documentation. The Tag-it protocol for Tag-it HF trans-
ponders is described in the Tag-it protocol, TI specification 11-04-21-002. Notes:
The transmission direction of the binary data depends on the defini-
tion of the selected RF Protocol and can be different between the command byte and the binary data (RF Protocol). For example: for ISO 15693 and ISO 14443 you must send the LSB first. The binary data response for the Tag-it protocol and the ISO 15693 protocol contains two additional zeros (0 0) in the end of frame, to indicate the end of transponder transmission. This sequence is decoded as 0 0 ES. The two zeros must be removed from the data string before any further processing. 4.3.2 Direct Mode In Direct Mode, the controller has to create all modulated signals sent to the TAG since the transmitter input is directly connected to the input line Din. This signal has the exact timing required by the TAG. Figure 13: Direct Mode Direct Mode Symbolic S1 cmd=direct mode ES1 Data = to be sent to TAG TAG data manchester coded TX off S1 new cmd Sclock Din Dout The Direct Mode is entered by S1, command (8 bits), ES1 and the Transceiver IC is then set to direct Mode. At this point, no carrier modulation has been applied to the TAG. After SCLOCK rises, DIN can directly control the modulation input, which is then directly connected to the RF modulator. The modulation depth 10% or 100%, the receiver channel settings and the demodu-
lation mode AM/FSK are defined by the command byte. The raw demodulated data
(Manchester coded) is available at DOUT and no further processing is performed by the Transceiver IC when operating in this mode. To exit this mode the SCLOCK line changes from high-to-low and the transmitter is switched off. 25 S6700 Multi-Protocol Transceiver IC - Reference Guide June 02 4.4 4.4.1 Register Configuration Write Data to Configuration Register The data bits following the command byte are written to the configuration register. Figure 14: Write Configuration Register Write to Configuration Register Symbolic S1 command=Write to Configuration Register b0 b7 data= Configuration data to write ES1 Sclock Din Dout Figure 14 represents the command Write to Configuration Register since the 8 bits of command are 01111101. The data stream illustrated in Figure 14 is 8 bits long. This sequence is used to define the active settings when operating in Register mode (see sequence Register Mode). The values for Bit 7 Idle Mode and bit 0
Manchester Decoder are also valid for Normal Mode. After the bit ES1, the command Write to Configuration Register is finished. A new bit S1 is expected to initiate a new sequence. 4.4.2 Read Data from Configuration Register Read Data from Configuration Register: The data after the command byte are the content of the registers and clocked out by the SCLOCK from the controller. Figure 15: Read from Configuration Register Read from Configuration Register Symbolic S1 command = Read from Configuration Register data = Configuration Register data on Dout ES1 b7 b0 Sclock Din Dout Symbolic S1 command = Read from Configuration Register b0 b7 data = Configuration data ES Sclock Din Dout Read from Configuration Register interupted by RC Figure 15 shows the Read from Configuration Register command, which is 01110001. The controller is reading the configuration register of the Transceiver IC. This has nothing to do with the presence of a TAG or not. The controller can consider this operation as reading a RAM via the three wires serial link interface. The control-
ler is allowed to send ES1 before having read all configuration bits if it does not need to know all bits. The order of the configuration bits inside the Transceiver IC is then important in case a specific part of the configuration is read frequently. After the bit ES1, the command Read from Configuration Register is finished. A new bit S1 is expected to initiate a new sequence. 26 June 02 Chapter 4. Protocol Definition 4.5 4.5.1 Communication FIFO Management Because the micro controller cannot control the timing of sending data to the TAG the Transceiver IC must store the data from the micro controller. The capacity of stor-
age being limited, management of the buffer must be implemented. The buffer is im-
plemented as a 16 bit FIFO. Figure 16: FIFO Management Symbolic S1 cmd data= to be sent to TAG ES1 FIFO Management Sclock Din Dout Note:
As long as DOUT is at level 1 it is not permitted to send a clock signal on the SCLOCK line. The FIFO management is shown in Figure 16. The Transceiver IC indicates that its buffer is full and asks the controller to stop sending data. The Transceiver IC does so by raising DOUT while SCLOCK=0. The controller must wait until DOUT returns to level 0 to send further data. The Transceiver IC indicates that its buffer is almost empty under the following conditions:
Table 8: Overview of #Bits present in FIFO
# Bits present in FIFO Mode DOUT is rising DOUT is falling Tag-it ISO 15693 1 out of 4 ISO 15693 1 out of 256 ISO 14443 16 16 16 16 3 2 7 3 Data is written with the commands Write ASIC, Normal Mode and Register Mode. The FIFO management is not needed for the Write ASIC command, since writing in the Transceiver IC is immediate. FIFO management will be used with the
Normal Mode and Register Mode commands. 27 S6700 Multi-Protocol Transceiver IC - Reference Guide June 02 4.5.2 Basic Request/Response The SCLOCK line becomes bi-directional. Note:
For the sake of clarity we have introduced a new convention: When the Transceiver IC drives the line SCLOCK the start of the sequence is marked S2 and the end ES2. DIN is always input for the Transceiver IC DOUT is always an output for the Transceiver IC SCLOCK is used by the Transceiver IC and the controller Figure 17: Basic Request/Response Basic Request / Response Symbolic S1 cmd data= to be sent to TAG ES1 TRAN1 S2 TAG data ES2 TRAN2 Sclock Din Dout a b c d e S1, cmd//, and ES1 are sent (cmd// = normal mode OR register mode). A SOF followed by the data and terminated by EOF is transmitted to the TAG by amplitude modulation of the carrier. (Remark: the FIFO management is not shown in figures 13, 15 and 17). In a typical case, the TAG will now send its answer to the request. The ASIC has to control the line SCLOCK since the data rate of the TAG will pace the data flow. 4.5.2.1 Definition TRAN1 During Transient 1 (TRAN1), the controller gives control of the SCLOCK line to the Transceiver IC: DIN =0 Time a: The bit ES1 is finished. Time b: The controller raises DIN, either to prepare a control mode change for the SCLOCK line or to prepare an ES1. Time c: DIN is falling. The controller definitely indicates that it will give the SCLOCK line control to the Transceiver IC. SCLOCK =0 and both the controller and the Transceiver IC are outputs. Time d: DIN rises showing that the controller leaves the control of the bus until DIN falls to ask the control of SCLOCK back. At time d, SCLOCK is still equal to 0 but the pin SCLOCK of the controller is an input and the pin SCLOCK of the Transceiver IC is an output. When the Transceiver IC has control of SCLOCK, it will send a S2 that corresponds to a SOF sent by the TAG, the data (7 bits in Figure 17) and an ES2 that corresponds to the EOF of the TAG. 4.5.2.2 Definition TRAN2:
During Transient 2, the controller regains control of SCLOCK: DIN =1 The controller indicates its intention to regain control over SCLOCK by setting DIN=0 and initiate a change by making a pulse on DIN. It is during this pulse that the line SCLOCK will change direction. 28 June 02 Chapter 4. Protocol Definition 4.5.3 Bi-directional SCLOCK Figure 18 shows an extreme case of successive changes of SCLOCK control. This example demonstrates the principle, its purpose is not to show a typical case. Even if this could be done, it is very unlikely that a user would implement such a case. Figure 18: Bi-directional SCLOCK Bi-directional SCLOCK TRAN1 TRAN2 ES1 TRAN1 data TRAN2 Symboli c Sclock Din Dout a b c d e f g h1 h2 i j k l m A classical TRAN1 is shown at times a, b and c of Figure 18. This is described in sec-
tion 4.5.2.1. At time d, the controller signals that it wants to take back control of SCLOCK. DIN rises at time e. Between time e and time f, SCLOCK=0 both Transceiver IC and con-
troller are outputs. At time f, only the controller is an output. At time g, the controller raises DIN to prepare an ES1. Between time h1 to h2, a classical TRAN1 is performed. At time h2, the Transceiver IC controls SCLOCK. At time i, the Transceiver IC raises DOUT to be ready to send a data 1 to the con-
troller as SCLOCK is rising. At the same time (before or after), the controller resets DIN showing it wants to take back the bus. The falling of DOUT while SCLOCK=1 is normally an ES2. At time k, the Transceiver IC resets SCLOCK to low. After this a TRAN2 can take place. At time l, both Transceiver IC and controller are outputs. At time m, the Trans-
ceiver IC is an input and the controller is an output. 29 S6700 Multi-Protocol Transceiver IC - Reference Guide June 02 4.5.4 Simultaneous Identification (SID) / Anti-collision Figure 19: Simultaneous Identification (SID) / Anti-collision Simultaneous Identification (SID) Symbolic S1 cmd data= to be sent to TAG ES1 TRAN1 S2 TAG data ES2 TRAN2 Sclock Din Dout a b c d e w o e b l e e s Symbolic ES1 TRAN1 S2 TAG data TRAN2 S1 new command Sclock Din Dout f When you have read section 4.5.3 you (controller software developer) have all the elements to establish a SID with the TAG, this is shown in Figure 19. The sequence S1, cmd//, data, ES1, will send to the TAG a SOF, Data (=SID re-
quest), EOF. The last EOF can normally be seen as the marker of the beginning of the first slot. The first TRAN1 allows the Transceiver IC to send the data received from the TAG. The first bit sent is S2 (corresponding to a SOF sent by the TAG), TAG data (7 bits on Figure 19), ES2 (corresponding to the EOF sent by the TAG). A TRAN2 gives back the SCLOCK to the controller. ES1 is then sent to modulate an EOF towards the TAG, delimiting a new slot. The next signals are TRAN1, S2, TAG data (only 4 bits) but at this time, the controller is not interested in continuing to read data. At time f, the controller resets DIN to ask for control of SCLOCK. The Transceiver IC stops the process TRAN2 since SCLOCK=1 by resetting DOUT. As soon as SCLOCK=0, the Transceiver IC ac-
knowledges it is ready to begin a TRAN2 by raising DOUT=1. A TRAN2 can now take place to give back the control to the controller. Finally, the controller decides to start a new sequence by sending S1, which com-
pletes the SID sequence. The two slots shown, as an example, are not typical since 16 slots may be used in normal operation. 30 June 02 Chapter 4. Protocol Definition 4.6 4.6.1 Power Management Idle Mode The Transceiver IC can be switched to Idle mode by configuring Bit 7 of the Config-
uration Register to 1 with the command Write to Configuration Register. In this mode, only the oscillator and the essential digital circuits are enabled. It can be switched out of Idle mode by configuring Bit 7 of the Configuration Register to 0. 4.6.2 Power Down Mode The Transceiver IC can be switched into Power Down Mode by sending the Power Down configuration command (01111110) as described in section 4.1.2 and Table 7. In Power Down Mode, the crystal will not be running, some analog circuitry may be shut down, the carrier will be off, the configuration bits remain unchanged. Consequently, the serial link (clocked by the crystal) will not be available. The con-
troller cannot communicate with the Transceiver IC in this mode. To wake the Transceiver IC up, the controller has to send a bit S1 that will trigger some asynchronous circuitry on board of the Transceiver IC. This action will reset
(asynchronously) the bit Power Down, and will restart the crystal oscillator. After a delay of 10 ms, the serial link will operate again. During a wake up phase, the controller will have to wait until the crystal oscillator has reached its nominal operating conditions again. The controller (after this delay) should initiate a new sequence (S1, cmd, and data, ES1). Note that the bit S1 used to wake up the Transceiver IC is not initiating a sequence. In practice, to write a new sequence to the Transceiver IC when the Transceiver IC is in Power Down Mode, the controller must do: S1, delay (10 ms), S1, cmd, data, ES1 (where cmd can be any command). The pin M_ERR is an output and has three functions:
It will rise during ES1 if the bit #0 (parity) is wrong in the command It will rise as soon as bad data is decoded by the Manchester decoder while receiving data. This tells the controller that the common bits of two Tags an-
swered at the same time within the same slot or the timing offset for synchro-
nizing of the Manchester decoder needs to be adjusted (see Appendix C -
Timing Register). If the FIFO Buffer is empty and the reader to transponder communication is finished then a 22 s pulse is generated on the M_ERR pin. 4.7 Pin M_ERR 31 Regulatory, Safety and Warranty Notices CHAPTER 5 Chapter 5:Regulatory, Safety and Warranty Notices This chapter provides important information about regulatory constraints and safety precautions.

June 02 Appendix A. Application Examples At 5 V, this circuit will output typically 200 mW RF power when a suitable matched 50 antenna is connected. At 3 V the output will be typically 80 mW RF power. Pro-
portionately lower RF outputs will result if you only have a simple resonating circuit. Where the transmitter is intended to be on all the time, it is recommended that the chip pad sizes and tracks are increased to provide a larger area for heat dissipation. Care should be taken with board design to avoid excessive capacitance. When board capacitance is too high, the value of the capacitance associated with the crystal may need reducing to avoid an unstable clock. The suggested circuit shows capacitor val-
ues of 22 pF. The Transceiver IC can be switched from 100% to 10% via the software. ISO 15693 specifies that the inlay should perform with modulation depths between 10% and 30% (in addition to 100%) and the required depth can be configured by changing re-
sistor R2 in the suggested circuit. Table 10 shows the resistance values required in to change the depth of modulation. Table 10: Modulation Resistor Values Modulation%

For test purposes the boundary scan signals can be feed to the pin M-ERR by setting bit D7. Tdelay M_ERR Conditions to set the timing offset:
The first rising edge of the boundary scan must be in front of the start of the tag response.
The first boundary scan pulse can be set by changing the Timing Offset Bits D6..D0.
The weight of one bit shifts Tdelay by 295 ns (4/13.56 MHz). Changing the value of this register is done with the command 0111 1011 followed by a 13-bit data stream. Example:
Set Tdelay to 311.31 s Send command 0111 1011 followed by the 13-bit data stream 1100 0000 1001 0. 39 S6700 Multi-Protocol Transceiver IC - Reference Guide June 02 Symbolic S1 command = Timing Setting data= Timing settings to write b7 b0 Sclock Din Dout Sclock Din Dout cont.data= Timing settings to write ES1 The changed setting remains active until the device is disconnected from power. 40 APPENDIX D Terms & Abbreviations Appendix D:Terms & Abbreviations A list of the abbreviations and terms used in various TI-RFID manuals can now be found in a separate manual:
