When the OFFCAL bit is set, inputs are disconnected and tied to AV
zero. Then, the user can perform a conversion. Use of the Calibration mode is not affected by AD1PCFG
contents nor channel input selection. Any analog input switches are disconnected from the A/D converter
in this mode. The conversion result is stored by the user software and used to compensate subsequent
conversions. This can be done by adding the two’s complement of the result obtained with the OFFCAL bit
set to all normal A/D conversions.
VCFG<2:0>: Voltage Reference Configuration bits
OFFCAL: Offset Calibration bit
1 = Converts to get the offset calibration value
0 = Coverts to get the actual input value
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 at the completion of conversion for each 16
1110 = Interrupts at the completion of conversion for each 15
.

.
0001 = Interrupts at the completion of conversion for each 2
0000 = Interrupts at the completion of conversion for each sample/convert sequence
BUFM: Buffer Mode Select bit
1 = Buffer configured as two 8-word buffers (ADC1BUFn<15:8> and ADC1BUFn<7:0>)
0 = Buffer 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
