VCFG<2:0>: Converter Voltage Reference Configuration bits
Unimplemented: Read as ‘0’
CSCNA: Scan Input Selections for CH0+ during Sample A bit
1 = Scan inputs
0 = Do not scan inputs
CHPS<1:0>: Selects Channels Utilized bits
When AD12B = 1, CHPS<1:0> is: U-0, Unimplemented, 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 buffer 0x8-0xF, user should access data in 0x0-0x7
0 = ADC is currently filling buffer 0x0-0x7, user should access data in 0x8-0xF
Unimplemented: Read as ‘0’
SMPI<3:0>: Selects Increment Rate for DMA Addresses bits or number of sample/conversion
operations per interrupt.
1111 = Increments the DMA address or generates interrupt after completion of every 16th
1110 = Increments the DMA address or generates interrupt after completion of every 15th
• • •
0001 = Increments the DMA address or generates interrupt after completion of every 2nd
0000 = Increments the DMA address or generates interrupt after completion of every
BUFM: Buffer Fill Mode Select bit
1 = Starts buffer filling at address 0x0 on first interrupt and 0x8 on next interrupt
0 = Always starts filling buffer at address 0x0
