Bit Field Type Reset Description
31-26 ADC_DCBIAS R X
DC Bias read by RADC during SAR mode The vaue is an unsigned
interger. It is used for debug only.
25 HPM_RAMP1_THMET R X
Indication of threshhold is met for hpm_ramp1
24 HPM_RAMP2_THMET R X
Indication of threshhold is met for hpm_ramp2
23 HPM_RAMP3_THMET R X
Indication of threshhold is met for hpm_ramp3
22-16 RESERVED R X
Software should not rely on the value of a reserved. Writing any
other value than the reset value may result in undefined behavior.
15-12 RAMPSTATE R X
xosc_hf amplitude compensation FSM This is identical to
STAT1.RAMPSTATE. See that description for encoding.
11-4 RESERVED R X
Software should not rely on the value of a reserved. Writing any
other value than the reset value may result in undefined behavior.
3 AMPCOMP_REQ R X
ampcomp_req
2 XOSC_HF_AMPGOOD R X
amplitude of xosc_hf is within the required threshold (set by DDI).
Not used for anything just for debug/status
1 XOSC_HF_FREQGOOD R X
frequency of xosc_hf is good to use for the digital clocks
0 XOSC_HF_RF_FREQGO R X
frequency of xosc_hf is within +/- 20 ppm and xosc_hf is good for
OD
radio operations. Used for SW to start synthesizer.
