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
1 = Channel 0 negative input is AN1
0 = Channel 0 negative input is VREF-
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
