22.3 Output Compare Mode
Output Compare mode compares the Timer register value with the value of one or two Compare registers, depending on its mode of operation. The Output Compare x module, on compare match events, has the ability to generate a single output transition or a train of output pulses. Like most PIC® MCU peripherals, the Output Compare x module can also generate interrupts on a compare match event.
Table 22-2 shows the various modes available in Output Compare modes.
