Comparator Configuration
The on-board comparator inputs, (GP0/CIN+, GP1/
CIN-), as well as the comparator output (GP2/COUT),
are steerable. The CMCON0, OPTION and TRIS
registers are used to steer these pins (see Figure 8-1).
If the Comparator mode is changed, the comparator
output level may not be valid for the specified mode
change delay shown in Table 12-1.
