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’
SMPI3:SMPI0: Sample/Convert Sequences Per Interrupt Selection bits
1111 = Interrupts at the completion of conversion for each 16th sample/convert sequence
1110 = Interrupts at the completion of conversion for each 15th sample/convert sequence
.....
0001 = Interrupts at the completion of conversion for each 2nd sample/convert sequence
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 (AD1BUFn<15:8> and AD1BUFn<7:0>)
0 = Buffer configured as one 16-word buffer (AD1BUFn<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
