Legend:

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

CMIDL: Stop in Idle Mode bit

1 = When device enters Idle mode, module does not generate interrupts. Module is still enabled

0 = Continue normal module operation in Idle mode

Unimplemented: Read as ‘0’

C2EVT: Comparator 2 Event bit

1 = Comparator output changed states

0 = Comparator output did not change states

C1EVT: Comparator 1 Event bit

1 = Comparator output changed states

0 = Comparator output did not change states

C2EN: Comparator 2 Enable bit

1 = Comparator is enabled

0 = Comparator is disabled

C1EN: Comparator 1 Enable bit

1 = Comparator is enabled

0 = Comparator is disabled

C2OUTEN: Comparator 2 Output Enable bit (1)

1 = Comparator output is driven on the output pad

0 = Comparator output is not driven on the output pad

C1OUTEN: Comparator 1 Output Enable bit (2)

1 = Comparator output is driven on the output pad

0 = Comparator output is not driven on the output pad

C2OUT: Comparator 2 Output bit

When C2INV = 0:

1 = C2 VIN+ > C2 VIN-

0 = C2 VIN+ < C2 VIN-

When C2INV = 1:

0 = C2 VIN+ > C2 VIN-

1 = C2 VIN+ < C2 VIN-

Note 1:

2:

If C2OUTEN = 1, the C2OUT peripheral output must be configured to an available RPx pin. See

Section 11.6 “Peripheral Pin Select” for more information.

If C1OUTEN = 1, the C1OUT peripheral output must be configured to an available RPx pin. See

Section 11.6 “Peripheral Pin Select” for more information.
