27.4.3.3.1 Timer Interrupts in Input Capture Modes

The module produces both timer interrupts (CCTxIF) as well as capture interrupts (CCPxIF) while operating in Input Capture mode. However, the timer interrupts only occur at the timer rollover, from FFFFh to 0000h, since there is no period register available to set the count period. If a shorter timer count period is desired, a second CCP module or external timer may be used to provide a synchronization source for the Input Capture time base.
