Dear TI and all,

The user guide of DLP-7970ABP show  pin connections to the launchpad. But the other 22 pins and V,I,G,R pins does not noticed.

From this thread, pin 11 is the MOD pin of TRF7970A. I'm interesting other pins on the DLP-7970ABP

    These signals are Voltage, Test, Ground and Reset for the Spi-By-Wire interface to the microcontroller that is **not** mounted to the Boosterpack under the shield.  The micro on the Launchpad is used to drive the RFID chip on the DLP-7970ABP BoosterPack. 

    Version 4.3 of the DLP-RFID2 module is also available with an MSP430F5342 as shown on the schematic on this page: http://www.dlpdesign.com/bpd/DLP-7970ABP-DS.pdf.   The Spi-By-Wire interface is provided for that version of the module.
