VCFG<2:0>: Converter Voltage Reference Configuration bits
Unimplemented: Read as ‘0’
CSCNA: Scan Input Selections for CH0+ during Sample A bit
1 = Scan inputs
0 = Do not scan inputs
CHPS<1:0>: Selects Channels Utilized bits
When AD12B = 1, CHPS<1:0> is: U-0, Unimplemented, Read as ‘0’
1x =Converts CH0, CH1, CH2 and CH3
01 =Converts CH0 and CH1
00 =Converts CH0
BUFS: Buffer Fill Status bit (only valid when BUFM = 1)
1 = A/D is currently filling second half of buffer, user should access data in first half
0 = A/D is currently filling first half of buffer, user should access data in second half
Unimplemented: Read as ‘0’
SMPI<3:0>: Selects Increment Rate for DMA Addresses bits or number of sample/conversion
operations per interrupt
1111 =Increments the DMA address or generates interrupt after completion of every 16th
1110 = Increments the DMA address or generates interrupt after completion of every 15th
• • •
0001 =Increments the DMA address or generates interrupt after completion of every 2nd
0000 = Increments the DMA address or generates interrupt after completion of every
BUFM: Buffer Fill Mode Select bit
1 = Starts filling first half of buffer on first interrupt and second half of buffer on next interrupt
0 = Always starts filling buffer from the beginning
ALTS: Alternate Input Sample Mode Select bit
1 = Uses channel input selects for Sample A on first sample and Sample B on next sample
0 = Always uses channel input selects for Sample A
