PIC24HJ32GP202/204 and PIC24HJ16GP304
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’
AD12B: 10-bit or 12-bit Operation Mode bit
1 = 12-bit, 1-channel ADC operation
0 = 10-bit, 4-channel ADC operation
FORM<1:0>: Data Output Format bits
For 10-bit operation:
11 = Reserved
10 = Reserved
01 = Signed integer (D
00 = Integer (D
For 12-bit operation:
11 = Reserved
10 = Reserved
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 = Reserved
101 = Reserved
100 = Reserved
011 = Reserved
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)
When AD12B = 1, SIMSAM is: U-0, Unimplemented, Read as ‘0’
1 = Samples CH0, CH1, CH2, CH3 simultaneously (when CHPS<1:0> = 1x); or
0 = Samples multiple channels individually in sequence
SSRC<2:0>
R/W-0
Samples CH0 and CH1 simultaneously (when CHPS<1:0> = 01)
