CH0NB: Channel 0 Negative Input Select for MUX B Multiplexer Setting bit
1 = Channel 0 negative input is AN1
0 = Channel 0 negative input is VR-
Unimplemented: Read as ‘0’
CH0SB<4:0>: Channel 0 Positive Input Select for MUX B⁽¹⁾
Other = Not available; do not use
11111 = No channel used; all inputs are floating; used for CTMU
11011 = Channel 0 positive input is the band gap divided-by-six reference (VBG/6)
11010 = Channel 0 positive input is the core voltage (VCAP)
11001 = Channel 0 positive input is the band gap reference (VBG)
11000 = Channel 0 positive input is the band gap divided-by-two reference (VBG/2)
10111 = Channel 0 positive input is AN23⁽²⁾

00001 = Channel 0 positive input is AN1
00000 = Channel 0 positive input is AN0
Note 1: Combinations not shown here (11100 to 11110) are unimplemented; do not use.
2: Channel 0 positive inputs, AN16 through AN23, are not available on 64-pin devices (PIC24FJXXXDAX06).
