... comparators in the PIC1 6C82X controlled by the CMCON register, which is defined in Table 16. 13. The CIS and CM2–CM0 bits work together to select the operation of the comparators, and the resulting ... the PIC microcontroller into a “watchdog” for a complex system. As is shown in Fig. 16. 8, the PIC microcontroller controls reset to the system processor. On powe...
