Only applicable when the buffer is used in FIFO mode (BUFREGEN = 0). In addition, BUFS is only used
when BUFM = 1.
PVCFG<1:0>: Converter Positive Voltage Reference Configuration bits
11 = Internal VRH2
10 = Internal VRH1
01 = External V
00 = AV
NVCFG0: Converter Negative Voltage Reference Configuration bits
1 = External V
0 = AV
OFFCAL: Offset Calibration Mode Select bit
1 = Inverting and non-inverting inputs of channel Sample-and-Hold are connected to AV
0 = Inverting and non-inverting inputs of channel Sample-and-Hold are connected to normal inputs
BUFREGEN: A/D Buffer Register Enable bit
1 = Conversion result is loaded into buffer location determined by the converted channel
0 = A/D result buffer is treated as a FIFO
CSCNA: Scan Input Selections for CH0+ During SAMPLE A bit
1 = Scan inputs
0 = Do not scan inputs
Unimplemented: Read as ‘0’
BUFS: Buffer Fill Status bit
1 = A/D is filling the upper half of the buffer; user should access data in the lower half
0 = A/D is filling the lower half of the buffer; user should access data in the upper half
SMPI<4:0>: Interrupt Sample Rate Select bits
11111 = Interrupts at the completion of conversion for each 32nd sample
11110 = Interrupts at the completion of conversion for each 31st sample



00001 = Interrupts at the completion of conversion for every other sample
00000 = Interrupts at the completion of conversion for each sample
BUFM: Buffer Fill Mode Select bit
1 = Starts buffer filling at AD1BUF0 on first interrupt and AD1BUF(n/2) on next interrupt
0 = Starts filling buffer at address, ADCBUF0, and each sequential address on successive interrupts
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
