VCFG<2:0>: Converter Voltage Reference Configuration bits
Unimplemented: Read as ‘0’
CSCNA: Input Scan Select bit
1 = Scan inputs for CH0+ during Sample MUXA
0 = Do not scan inputs
CHPS<1:0>: Channel Select bits
In 12-bit mode, (AD21B = 1), CHPS<1:0> is unimplemented and is 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 = ADC is currently filling the second half of the buffer. The user application should access data in the
0 = ADC is currently filling the first half of the buffer. The user application should access data in the
SMPI<4:0>: Increment Rate bits
When ADDMAEN = 0:
x1111 = Generates interrupt after completion of every 16th sample/conversion operation
x1110 = Generates interrupt after completion of every 15th sample/conversion operation

x0001 = Generates interrupt after completion of every 2nd sample/conversion operation
x0000 = Generates interrupt after completion of every sample/conversion operation
When ADDMAEN = 1:
11111 = Increments the DMA address after completion of every 32nd sample/conversion operation
11110 = Increments the DMA address after completion of every 31st sample/conversion operation

00001 = Increments the DMA address after completion of every 2nd sample/conversion operation
00000 = Increments the DMA address after completion of every sample/conversion operation
BUFM: Buffer Fill Mode Select bit
1 = Starts buffer filling the first half of the buffer on the first interrupt and the second half of the buffer
0 = Always starts filling the buffer from the start address.
ALTS: Alternate Input Sample Mode Select bit
1 = Uses channel input selects for Sample MUXA on first sample and Sample MUXB on next sample
0 = Always uses channel input selects for Sample MUXA
