Description
DC Bias read by RADC during SAR mode
The vaue is an unsigned interger. It is used for debug only.
Indication of threshhold is met for hpm_ramp1
Indication of threshhold is met for hpm_ramp2
Indication of threshhold is met for hpm_ramp3
Software must not rely on the value of a reserved. Writing any other
value than the reset value may result in undefined behavior.
xosc_hf amplitude compensation FSM
This is identical to STAT1.RAMPSTATE. See that description for
encoding.
Software must not rely on the value of a reserved. Writing any other
value than the reset value may result in undefined behavior.
ampcomp_req
amplitude of xosc_hf is within the required threshold (set by DDI).
Not used for anything just for debug/status
frequency of xosc_hf is good to use for the digital clocks
frequency of xosc_hf is within +/- 20 ppm and xosc_hf is good for
radio operations. Used for SW to start synthesizer.
