2.1 RF-BB interface (ST_CDSP_RF_BB_IF_TEST)
RF_BB_IF test (86) tests the functionality of the RAP3G/HINKU/VINKU serial interface & reset lines. If this
test fails, it means that there’s a problem programming Hinku and or Vinku and all of the following
tests cannot give correct data.
Tested signals: VBAT_ASIC, VDIG, VREFRF01, VXO, RFBUSDAT, RFBUSCLK, RFBUSENA, RXRESETX, TXRESETX
Error code for this self test is given in format:
• 0xyy, 0xzz
,where 0xyy, 0xzz part is the total error code: 0xyyzz
