Type Reset Description
R/W 0h
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
0h = Selects RTC_CH2_EV as start signal
1h = Selects AUX_COMPA as start signal
2h = Selects AUX_COMPB as start signal
3h = Selects TDC_DONE as start signal
4h = Selects TIMER0_EV as start signal
5h = Selects TIMER1_EV as start signal
6h = Selects SMPH_AUTOTAKE_DONE as start signal
7h = Reserved do not use
8h = Reserved do not use
9h = No event selected
Ah = No event selected
Bh = Selects AON_SW as start signal
Ch = Selects AON_PROG_WU as start signal
Dh = Selects AUXIO0 as start signal
Eh = Selects AUXIO1 as start signal
Fh = Selects AUXIO2 as start signal
10h = Selects AUXIO3 as start signal
11h = Selects AUXIO4 as start signal
12h = Selects AUXIO5 as start signal
13h = Selects AUXIO6 as start signal
14h = Selects AUXIO7 as start signal
15h = Selects AUXIO8 as start signal
16h = Selects AUXIO9 as start signal
17h = Selects AUXIO10 as start signal
18h = Selects AUXIO11 as start signal
19h = Selects AUXIO12 as start signal
1Ah = Selects AUXIO13 as start signal
1Bh = Selects AUXIO14 as start signal
1Ch = Selects AUXIO15 as start signal
1Dh = Selects ACLK_REF as start signal
1Eh = Selects MCU_EV as start signal
1Fh = Selects ADC_IRQ as start signal
R 0h
Software should not rely on the value of a reserved. Writing any
other value than the reset value may result in undefined behavior.
R/W 0h
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.
