THROUGH 3) (CONTINUED)
bit 4
bit 3-2
bit 1-0
CREF: Comparator Reference Select bits (non-inverting input)
1 = Non-inverting input connects to the internal CVREF voltage
0 = Non-inverting input connects to the CXINA pin
Unimplemented: Read as ‘0’
CCH<1:0>: Comparator Channel Select bits
11 = Inverting input of the comparator connects to the internal selectable reference voltage specified by
the CVREFM<1:0> bits in the CVRCON register
10 = Inverting input of the comparator connects to the CXIND pin
01 = Inverting input of the comparator connects to the CXINC pin
00 = Inverting input of the comparator connects to the CXINB pin
