START_SRC
R/W
X
Selected source for ADC conversion start event. The start source
selected by this field is OR'ed with any trigger coming from writes to
ADCTRIG.START. If it is desired to only trigger ADC conversions by
writes to ADCTRIG.START one should select NO_EVENT<n> here

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.

CMD
R/W
X
ADC interface control command
0h = ADC interface disabled
1h = ADC interface enabled
3h = ADC FIFO flush. Note that CMD needs to be set to 'EN' again
for FIFO to be functional after a flush. A flush takes two clock
periods on the AUX clock to finish.
