The following reference values are valid for a 3 V supply:
0: 1.85 V (default)
1: 1.95 V
2: 1.75 V
3: 1.65 V
Description
Description
1: enable the synthesizer calibration state machine
0: disable the synthesizer calibration state machine
1: enable receiver baseband filter (RXBB) calibration
0: disable receiver baseband filter (RXBB) calibration
Description
1: synthesizer calibration finished successfully
0: synthesizer calibration in progress

1: complete
0: in progress (valid while RXBB_CAL_EN = 1)
Description
RXBB reference oscillator calibration overwrite word
1: enable RXBB reference oscillator calibration word overwrite mode
0: disable RXBB reference oscillator calibration word overwrite mode
Description
Filtering modes
00: normal operation (no filter)
01: unfiltered AGC loop, filtered readback (updated upon MCR read)
10: unfiltered AGC loop, filtered readback (update at AGC clock rate)
11: filtered AGC loop, filtered readback
Bring low to power down the ADC reference
