14.1.4
There are four prescaler settings specified by the
CCPxM<3:0> bits of the CCPxCON register. Whenever
the CCP module is turned off, or the CCP module is not
in Capture mode, the prescaler counter is cleared. Any
Reset will clear the prescaler counter.
Switching from one capture prescaler to another does
not clear the prescaler and may generate a false
interrupt. To avoid this unexpected operation, turn the
module off by clearing the CCPxCON register before
changing the prescaler.

Capture mode requires a 16-bit TimerX module for use
as a time base. There are four options for driving the
16-bit TimerX module in Capture mode. It can be driven
by the system clock (F
