6.0
The PIC12F629/675 devices have one analog
comparator. The inputs to the comparator are
multiplexed with the GP0 and GP1 pins. There is an
on-chip Comparator Voltage Reference that can also
REGISTER 6-1:

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

GP2 can be configured as the comparator output.
The Comparator Control Register (CMCON), shown
in Register 6-1, contains the bits to control the
comparator.
