Legend:

R = Readable bit

-n = Value at POR

W = Writable bit

‘1’ = Bit is set

U = Unimplemented bit, read as ‘0’

‘0’ = Bit is cleared

x = Bit is unknown

CH0NB: Channel 0 Negative Input Select for Sample B bit

Same definition as bit 7.

Unimplemented: Read as ‘0’

CH0SB<4:0>: Channel 0 Positive Input Select for Sample B bits(1)

11111 = Channel 0 positive input is AN31

11110 = Channel 0 positive input is AN30

00010 = Channel 0 positive input is AN2

00001 = Channel 0 positive input is AN1

00000 = Channel 0 positive input is AN0

CH0NA: Channel 0 Negative Input Select for Sample A bit

1 = Channel 0 negative input is AN1

0 = Channel 0 negative input is VREF-

Unimplemented: Read as ‘0’

CH0SA<4:0>: Channel 0 Positive Input Select for Sample A bits(1)

11111 = Channel 0 positive input is AN31

11110 = Channel 0 positive input is AN30

•

00010 = Channel 0 positive input is AN2

00001 = Channel 0 positive input is AN1

00000 = Channel 0 positive input is AN0

Note 1: ADC2 can only select AN0 through AN15 as positive input.
