Legend:
S = Bit is set only -
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared x = Bit is unknown
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
bit 7
bit 6
bit 5
bit 4
bit 3
bit 2
SR1: SR Latch Configuration bit(2)
1= C2OUT pin is the latch Q output
0= C2OUT pin is the C2 comparator output
SR0: SR Latch Configuration bits(2)
1= C1OUT pin is the latch Q output
0= C1OUT pin is the C1 Comparator output
C1SEN: C1 Set Enable bit
1= C1 comparator output sets SR latch
0= C1 comparator output has no effect on SR latch
C2REN: C2 Reset Enable bit
1= C2 comparator output resets SR latch
0= C2 comparator output has no effect on SR latch
PULSS: Pulse the SET Input of the SR Latch bit
1= Triggers pulse generator to set SR latch. Bit is immediately reset by hardware.
0= Does not trigger pulse generator
PULSR: Pulse the Reset Input of the SR Latch bit
1= Triggers pulse generator to reset SR latch. Bit is immediately reset by hardware.
0= Does not trigger pulse generator
bit 1
bit 0
Unimplemented: Read as ‘0’
FVREN: Fixed Voltage Reference Enable bit
1= 0.6V Reference FROM INTOSC LDO is enabled
0= 0.6V Reference FROM INTOSC LDO is disabled
Note 1: The CxOUT bit in the CMxCON0 register will always reflect the actual comparator output (not the level on
the pin), regardless of the SR latch operation.
2: To enable an SR Latch output to the pin, the appropriate CxOE and TRIS bits must be properly
configured.
