ADON: ADC Operating Mode bit
1 = ADC module is operating
0 = ADC is off
Unimplemented: Read as ‘0’
ADSIDL: Stop in Idle Mode bit
1 = Discontinue module operation when device enters Idle mode
0 = Continue module operation in Idle mode
Unimplemented: Read as ‘0’

11 = Signed fractional (D
10 = Fractional (D
01 = Signed integer (D
00 = Integer (D
SSRC<2:0>: Sample Clock Source Select bits
111 = Internal counter ends sampling and starts conversion (auto-convert)
110 = CTMU
101 = Reserved
100 = Reserved
011 = Motor Control PWM interval ends sampling and starts conversion
010 = GP timer 3 compare ends sampling and starts conversion
001 = Active transition on INT0 pin ends sampling and starts conversion
000 = Clearing sample bit ends sampling and starts conversion
Unimplemented: Read as ‘0’
SIMSAM: Simultaneous Sample Select bit (applicable only when CHPS<1:0> = 01 or 1x)
1 = Samples CH0, CH1, CH2, CH3 simultaneously (when CHPS<1:0> = 1x); or
0 = Samples multiple channels individually in sequence
ASAM: ADC Sample Auto-Start bit
1 = Sampling begins immediately after last conversion. SAMP bit is auto-set.
0 = Sampling begins when SAMP bit is set
SAMP: ADC Sample Enable bit
1 = ADC sample-and-hold amplifiers are sampling
0 = ADC sample-and-hold amplifiers are holding
If ASAM = 0, software can write ‘1’ to begin sampling. Automatically set by hardware if ASAM = 1.
If SSRC = 000, software can write ‘0’ to end sampling and start conversion. If SSRC ≠ 000,
automatically cleared by hardware to end sampling and start conversion.
