Figure 4 FIFO Block Diagram It writes TX FIFO in TX mode by W_TX_PAYLOAD and W_TX_NO_ACK instructions. If MAX_RT interruption, data will be cleared in the TX FIFO. It reads PAYLOAD in RX FIFO in receiving mode by R_RX_PAYLOAD, and it reads the length of the PAYLOAD by R_RX_PL_WID instruction. FIFO_STATUS register indicates FIFO states. http://www.panchip.com Copyright 2015 Panchip Microelectronics, Ltd.

The XN297L is a slave terminal, SPI transfer rate depends on the MCU interface speed, and the maximum data transfer rate is 8 Mbps. SPI interface is a standard SPI interface are shown in table 5, you can use the general I/O for MCU simulation SPI interface. CSN pin to 0, SPI interface instructions to be performed. From 1 to 0 a CSN pin changes execute one instruction. After the change from 1 to 0 CSN pin can be read by MISO status register contents.

The R_REGISTER and W_REGISTER commands can operate on single or multi-byte registers. When accessing multi-byte registers, firstly read or write the MSBit of LSByte. Terminate the writing before all bytes in a multi-byte register are written, then it leaves the unwritten MSByte(s) unchanged. For example, the LSByte of RX_ADDR_P0 can be modified by writing only one byte to the RX_ADDR_P0 register. 777...222 SPISPISPI Timing Timing Timing Figure 5 SPI read operation Figure 6 SPI Write Operation http://www.panchip.com Copyright 2015 Panchip Microelectronics, Ltd.

Co 2.4GHz Module configuration bits. FCC Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

-- Reorient or relocate the receiving antenna.

-- Increase the separation between the equipment and receiver.

-- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

-- Consult the dealer or an experienced radio/TV technician for help. 15.19 Labeling requirements. This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. 15.21 Information to user. Any Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. RF exposure This equipment complies with FCC and ISED radiation exposure limits set forth for an uncontrolled environment. The RF exposure compliance of the distance of 0 mm between the radiator and your body. Antenna gain must be below 0.4dBi. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. The host end product must include a user manual that clearly defines operating requirements and conditions that must be observed to ensure compliance with current FCC RF exposure guidelines. For portable devices, in addition to above, a separate approval is required to satisfy the SAR requirements of FCC Part 2.1093. If the device is used for other equipment that separate approval is required for all other operating configurations, including portable configurations with respect to 2.1093 and different antenna configurations. Labelling Requirements for the Host device The host device shall be properly labeled to identify the modules within the host device. The certification label of the module shall be clearly visible at all times when installed in the host device, otherwise the host device must be labelled to display the FCC ID and ISED of the module, preceded by the words "Contains transmitter module", or the word "Contains", or similar wording expressing the same meaning, as follows:

Model: 2.4G module Contains FCC ID2APYU-DKL1613 The host OEM user manual must also contain clear instructions on how end users canfind and/or access the module and the FCC ID and ISED. Model: 2.4G module Contains FCC ID2APYU-DKL1613 The transmitter module may not be co-located with any other transmitter or antenna. Module Antenna Type: Integral Antenna,ANT Gain: 0.4dBi http://www.panchip.com Copyright 2015 Panchip Microelectronics, Ltd. Co 2.4GHz Module OEM Statement a. The module manufacturer must show how compliance can be demonstrated only for specific host or hosts b. The module manufacturer must limit the applicable operating conditions in which t transmitter will be used, and c. The module manufacturer must disclose that only the module grantee can make the te evaluation that the module is compliant in the host. When the module grantee either refuses to make this evaluation, or does not think it is necessary, the module certification is rendered invalid for use in the host, and the host manufacturer has no choice other than to use a different module, or take responsibility ( 2.929) and obtain a new FCC ID for the product. d. The module manufacturer must provide the host manufacturer with the follow requirements:

e. The host manufacturer is responsible for additional testing to verify compliance as composite system. When testing the host device for compliance with Part 15 Subpart B, the host manufacturer is required to show compliance with Part 15 Subpart B while the transmitter module(s) are installed and operating. The modules should be transmitting and the evaluation should confirm that the modules intentional emissions are compliant (i.e. fundamental and out of band emissions). Validity of using the module certification:

In the event that these conditions cannot be met (for example certain laptop configurations or co-location with another transmitter), then the FCC authorization for this module in combination with the host equipment is no longer considered valid and the FCC ID of the module cannot be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization. In such cases, please involve a FCC certification specialist in order to determine if a Permissive Class II Change or new Certification is required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed (for example, digital device emissions, PC peripheral requirements, etc.). The end-product may need Verification testing, Declaration of Conformity testing, a Permissive Class II Change or new Certification. Please involve a FCC certification specialist in order to determine what will be exactly applicable for the end-product.
