COMPARATOR MODULE
The comparator module contains one Analog
comparator. The inputs to the comparator are
multiplexed with GP0 and GP1 pins. The output of the
comparator can be placed on GP2.
The CMCON0 register, shown in Register 8-1, controls
the comparator operation. A block diagram of the
comparator is shown in Figure 8-1.

Overrides T0CS bit for TRIS control of GP2.
When the comparator is turned on, these control bits assert themselves. When the comparator is off, these
bits have no effect on the device operation and the other control registers have precedence.
