The CMxIF bit is automatically set any time this mode is selected and must be cleared by the application
after the initial configuration.
CON: Comparator Enable bit
1 = Comparator is enabled
0 = Comparator is disabled
COE: Comparator Output Enable bit
1 = Comparator output is present on the CxOUT pin (assigned in the PPS module)
0 = Comparator output is internal only
CPOL: Comparator Output Polarity Select bit
1 = Comparator output is inverted
0 = Comparator output is not inverted
EVPOL<1:0>: Interrupt Polarity Select bits
11 = Interrupt generation on any change of the output
10 = Interrupt generation only on high-to-low transition of the output
01 = Interrupt generation only on low-to-high transition of the output
00 = Interrupt generation is disabled
CREF: Comparator Reference Select bit (non-inverting input)
1 = Non-inverting input connects to internal CV
0 = Non-inverting input connects to CxINA pin
CCH<1:0>: Comparator Channel Select bits
11 = Inverting input of the comparator connects to V
00 = Inverting input of the comparator connects to CxINB pin
Unimplemented: Read as ‘0’
COUT<2:1>: Comparator x Status bits
If CPOL = 0 (non-inverted polarity):
1 = Comparator V
0 = Comparator V
If CPOL = 1 (inverted polarity):
1 = Comparator V
0 = Comparator V
