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>: Select 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 (valid only when BUFM = 1)
1 = ADC is currently filling second half of buffer, user should access data in the first half
0 = ADC is currently filling first half of buffer, user application should access data in the second half
Unimplemented: Read as ‘0’
SMPI<3:0>: Sample/Convert Sequences Per Interrupt Selection bits
1111 = Interrupts at the completion of conversion for each 16th sample/convert sequence
1110 = Interrupts at the completion of conversion for each 15th sample/convert sequence

0001 = Interrupts at the completion of conversion for each 2nd sample/convert sequence
0000 = Interrupts at the completion of conversion for each sample/convert sequence
BUFM: Buffer Fill Mode Select bit
1 = Starts filling first half of buffer on first interrupt and the 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
