48 / 136 page  PIC16C64X & PIC16C66X DS30559A-page 48 Preliminary © 1996 Microchip Technology Inc. 7.1 Comparator Configuration There are eight modes of operation for the comparators. The CMCON register is used to select the mode. Figure 7-2 shows the eight possible modes. The TRISA register controls the data direction of the comparator pins for each mode. If the comparator mode is changed, the comparator output level may not be valid for the specified mode change delay shown in Table 12-2. Note: Comparator interrupts should be disabled during a comparator mode change other- wise a false interrupt may occur.

D = Digital Input. CIS (CMCON<3>) is the Comparator Input Switch. |
