a. When J2 of SOP1 is short connected, J1 of SOP2 & J3 of SOP0 are disconnected(SOP[2,1,0]=010), the module is in flash programming mode. Firmware could be burned into flash via UART0_TX and UART0_RX. b. When J1 of SOP2,J2 of SOP1 and J3 of SOP0 are disconnected (SOP [2,1,0]=000), the module is in the functional module+ 4 Wire JTAG mode. c. When J3 of SOP0 is short connected,J2 of SOP1 and J1 of SOP2 are disconnected (SOP
[2,1,0]=001), the module is in the functional module+ 2 Wire JTAG mode. TEL: 0755-86329829 ADD: A 8 2 WEB: www.szrfstar.com FAX: 0755-86329413 2. Pin Assignment ShenzhenRFstarTechnologyCo.,Ltd.

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. 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. Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. If the FCC identification number is not visible when the module is installed inside the host, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following:
Contains Transmitter Module Contains FCC ID:2ABN2-RS3220B1 or Contains FCC ID: 2ABN2-RS3220B1 Any similar wording that expresses the same meaning may be used. RF warning statement:
The device has been evaluated to meet general RF exposure requirement. The device can be used in public exposure condition without restriction. This device should be installled and operated with minimum distance 20cm between the radiator and your body.
