CEN: 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
0 = Comparator output is internal only
CPOL: Comparator Output Polarity Select bit
1 = Comparator output is inverted
0 = Comparator output is not inverted
Unimplemented: Read as ‘0’
CEVT: Comparator Event bit
1 = Comparator event that is defined by EVPOL<1:0> has occurred; subsequent triggers and interrupts
0 = Comparator event has not occurred
COUT: Comparator Output bit
When CPOL = 0:
1 = V
0 = V
When CPOL = 1:
1 = V
0 = V
EVPOL<1:0>: Trigger/Event/Interrupt Polarity Select bits
11 = Trigger/event/interrupt is generated on any change of the comparator output (while CEVT = 0)
10 = Trigger/event/interrupt is generated on transition of the comparator output:
01 = Trigger/event/interrupt is generated on transition of comparator output:
00 = Trigger/event/interrupt generation is disabled
Unimplemented: Read as ‘0’
