bit 7 bit 0
Legend: C = Clearable bit
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 15 CMIDL: Stop in Idle Mode bit
1 = When the device enters Idle mode, the module does not generate interrupts; module is still enabled
0 = Continues normal module operation in Idle mode
bit 14 Unimplemented: Read as ‘0’
bit 13 C2EVT: Comparator 2 Event bit
1 = Comparator output changed states
0 = Comparator output did not change states
bit 12 C1EVT: Comparator 1 Event bit
1 = Comparator output changed states
0 = Comparator output did not change states
bit 11 C2EN: Comparator 2 Enable bit
1 = Comparator is enabled
0 = Comparator is disabled
bit 10 C1EN: Comparator 1 Enable bit
1 = Comparator is enabled
0 = Comparator is disabled
bit 9 C2OUTEN: Comparator 2 Output Enable bit
1 = Comparator output is driven on the output pad
0 = Comparator output is not driven on the output pad
bit 8 C1OUTEN: Comparator 1 Output Enable bit
1 = Comparator output is driven on the output pad
0 = Comparator output is not driven on the output pad
bit 7 C2OUT: Comparator 2 Output bit
When C2INV =
0:
1 =C2 VIN+ > C2 VIN-
0 =C2 V
IN+ < C2 VIN-
When C2INV = 1:
0 =C2 VIN+ > C2 VIN-
1 =C2 V
IN+ < C2 VIN-
bit 6 C1OUT: Comparator 1 Output bit
When C1INV = 0:
1 =C1 VIN+ > C1 VIN-
0 =C1 V
IN+ < C1 VIN-
When C1INV =
1:
0 =C1 VIN+ > C1 VIN-
1 =C1 V
IN+ < C1 VIN-
