ADON: A/D Operating Mode bit
1 = A/D converter module is operating
0 = A/D converter 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
ADDMABM: DMA Buffer Build Mode bit
1 = DMA buffers are written in the order of conversion. The module will provide an address to the
0 = DMA buffers are written in Scatter/Gather mode. The module will provide a scatter/gather address
Unimplemented: Read as ‘0’
AD12B: 10-bit or 12-bit Operation Mode bit
1 = 12-bit, 1-channel A/D operation
0 = 10-bit, 4-channel A/D 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 (Timer3 for ADC1, Timer5 for ADC2) compare ends sampling and starts conversion
001 = Active transition on INTx pin ends sampling and starts conversion
000 = Clearing sample bit ends sampling and starts conversion
Unimplemented: Read as ‘0’
