8.0
The comparator module contains one analog com-
parator. The inputs to the comparator are multiplexed
with I/O port pins, GP0 and GP1, while the outputs are
multiplexed to GP2. An on-chip Comparator Voltage

CMCON0 – COMPARATOR CONTROL REGISTER 0 (ADDRESS: 19h)
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 CM<2:0> = 110 or 101:
1 = V
0 = V
CM<2:0>: Comparator Mode bits
Figure 8-3 shows the Comparator modes and CM<2:0> bit settings.
