VCFG<2:0>: Voltage Reference Configuration bits
Reserved: Maintain as ‘0’
Unimplemented: Read as ‘0’
CSCNA: Scan Input Selections for the CH0+ S/H Input for MUX A Input Multiplexer Setting bit
1 = Scan inputs
0 = Do not scan inputs
Unimplemented: Read as ‘0’
BUFS: Buffer Fill Status bit (valid only when BUFM = 1)
1 = A/D is currently filling buffer, 10-1F, user should access data in 00-0F
0 = A/D is currently filling buffer, 00-0F, user should access data in 10-1F
SMPI<4:0>: Sample/Convert Sequences Per Interrupt Selection bits
11111 = Interrupts at the completion of conversion for each 32
11110 = Interrupts at the completion of conversion for each 31

.
00001 = Interrupts at the completion of conversion for each 2
00000 = Interrupts at the completion of conversion for each sample/convert sequence
BUFM: Buffer Mode Select bit
1 = Buffer is configured as two 16-word buffers (ADC1BUFn<31:16> and ADC1BUFn<15:0>)
0 = Buffer is configured as one 32-word buffer (ADC1BUFn<31:0>)
ALTS: Alternate Input Sample Mode Select bit
1 = Uses MUX A input multiplexer settings for the first sample, then alternates between MUX B and
0 = Always uses the MUX A input multiplexer settings
