VCFG<2:0>: Voltage Reference Configuration bits
Reserved: Maintain as ‘0’
Unimplemented: Read as ‘0’
CSCNA: Scan Input Selections for 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 08-0F; user should access data in 00-07
0 = A/D is currently filling buffer 00-07; user should access data in 08-0F
Unimplemented: Read as ‘0’
SMPI<3:0>: Sample/Convert Sequences Per Interrupt Selection bits
1111 = Interrupts are at the completion of conversion for each 16th sample/convert sequence
1110 = Interrupts are at the completion of conversion for each 15th sample/convert sequence
.....
0001 = Interrupts are at the completion of conversion for each 2nd sample/convert sequence
0000 = Interrupts are at the completion of conversion for each sample/convert sequence
BUFM: Buffer Mode Select bit
1 = Buffer is configured as two 8-word buffers (ADC1BUFn<15:8> and ADC1BUFn<7:0>)
0 = Buffer is configured as one 16-word buffer (ADC1BUFn<15:0>)
ALTS: Alternate Input Sample Mode Select bit
1 = Uses MUX A input multiplexer settings for first sample, then alternates between MUX B and
0 = Always uses MUX A input multiplexer settings
VCFG1
R/W-0
MUX A input multiplexer settings for all subsequent samples
