  1. RSSI TRF7960EVM DIRECTIONS

  2. STEP 1: SET PROTOCOL AND CHECK REGISTER SETTINGS

  3. SCOPE SCREEN SHOT IN SPI MODE SET PROTOCOL(ISO15693, HIGH DATA RATE, TX_ON)

  4. STEP 2: SET RX WITH DIRECT COMMAND 1517

  5. SCOPE SCREEN SHOT IN SPI MODE SET RECEIVER 1517 (GUI) or 97h (actual command) THIS IS DUMMY CLK 1 0 0 1 0 1 1 1

  6. STEP 3: CHECK INTERNAL RF WITH DIRECT COMMAND 1518 OR EXTERNAL RF WITH DIRECT COMMAND 1519 DIRECT COMMAND 1518 (CHECK INTERNAL RF) SHOWN

  7. SCOPE SCREEN SHOT IN SPI MODE CHECK INTERNAL RF 1518 (GUI) or 98h (actual command) THIS IS DUMMY CLK

  8. STEP 4: READ REGISTER WITH DIRECT COMMAND 12ØF (FROM ISSUING DIRECT COMMAND 1518 PRIOR TO DIRECT COMMAND 120F SHOWN) Internal RSSI Value (in this case)

  9. SCOPE SCREEN SHOT IN SPI MODE READ RSSI VALUE 120F (GUI) or 4Fh (actual command)RSSI VALUE (FROM CHECK EXTERNAL RF = 5Ch) THIS IS DUMMY CLK THIS IS 5Ch

  10. ALT STEP 4: READ REGISTER WITH DIRECT COMMAND 12ØF (FROM ISSUING DIRECT COMMAND 1519 PRIOR TO DIRECT COMMAND 120F SHOWN) External RSSI Value (in this case)

  11. SCOPE SCREEN SHOT IN SPI MODE READ RSSI VALUE 120F (GUI) or 4Fh (actual command)RSSI VALUE (FROM CHECK INTERNAL RF = 78h) THIS IS DUMMY CLK THIS IS 78h

  12. STEP 5: CHANGE CHIP STATUS CONTROL REGISTER TO ’01’ (TURNS OFF TRANSMITTER)

  13. STEP 6: SET RX WITH DIRECT COMMAND 1517

  14. STEP 7: CHECK INTERNAL RF WITH DIRECT COMMAND 1518 OR EXTERNAL RF WITH DIRECT COMMAND 1519 DIRECT COMMAND 1518 (CHECK INTERNAL RF) SHOWN

  15. STEP 8: READ REGISTER WITH DIRECT COMMAND 12ØF (FROM ISSUING DIRECT COMMAND 1518 PRIOR TO DIRECT COMMAND 120F SHOWN) Internal RSSI Value (in this case)

  16. ALT STEP 8: READ REGISTER WITH DIRECT COMMAND 12ØF (FROM ISSUING DIRECT COMMAND 1519 PRIOR TO DIRECT COMMAND 120F SHOWN) External RSSI Value (in this case)

  17. SCOPE SCREEN SHOT IN SPI MODE READ RSSI VALUE 120F (GUI) or 4Fh (actual command)RSSI VALUE (FROM CHECK INTERNAL RF = 40h) THIS IS DUMMY CLK THIS IS 40h
