2.5 RxTSP(A/B) Configuration Memory
The block diagrams of the RxTSPA and RxTSPB modules are exactly the same. The control
structure is shown in Figure 23. The tables in this chapter describe the control registers of
RxTSPA and RxTSPB modules.
There is one BIST logic per RxTSPA and RxTSPB. The BIST control structure is
shown in Figure 26.

CAPTURE: Captures value, selected by CAPSEL[1:0].
0 – (default)
0-to-1 – positive edge captures value, selected by CAPSEL[1:0]
CAPSEL[1:0]: Selects what parameters to capture to memory (addresses 0x0400E
and 0x0400F)
00 – RSSI (default)
01 – ADCI and ADCQ (see CAPSEL_ADC register for more information)
10 – BSIGI and BSTATE
11 – BSIGQ and BSTATE
CAPSEL_ADC: Selects ADC value source to be captured, when CAPSEL[1:0] = 01.
0 – RxTSP input (default)
1 – RxTSP output
Reserved
TSGFC: TSG full scale control.
0 – -6dB (default)

TSGDCLDQ: Load TSG DC Q register with value from DC_REG[15:0].
0 – No action (default)
0-to-1 – positive edge loads TSG's DC register Q.
TSGDCLDI: Load TSG DC I register with value from DC_REG[15:0].
0 – No action (default)
0-to-1 – positive edge loads TSG's DC register I.
TSGSWAPIQ: Swap signals at test signal generator's output.
0 – Do not swap (default)
1 – Swap I an Q signal sources comming from TSG
TSGMODE: Test signal generator mode.
0 – NCO (default)
1 – DC source
INSEL: Input source of TxTSP:
