The PIC16F630/676 devices have one analog compar-
ator. The inputs to the comparator are multiplexed with
the RA0 and RA1 pins. There is an on-chip Comparator

bit 7
Unimplemented: Read as ‘0’
COUT: Comparator Output bit
When CINV = 0:
1 = V
0 = V
When CINV = 1:
1 = V
0 = V
Unimplemented: Read as ‘0’
CINV: Comparator Output Inversion bit
1 = Output inverted
0 = Output not inverted
CIS: Comparator Input Switch bit
When CM2:CM0 = 110 or 101:
1 = V
0 = V
CM2:CM0: Comparator Mode bits
Figure 6-2 shows the Comparator modes and CM2:CM0 bit settings

of the comparator. In addition, RA2 can be configured
as the comparator output. The Comparator Control
Register (CMCON), shown in Register 6-1, contains
the bits to control the comparator.
