PIC16F785/HV785
8.3.3
In Sleep mode, all clock sources are disabled. Timer2
will not increment and the state of the module will not
change. If the RC5/CCP1 pin is driving a value, it will
continue to drive that value. When the device wakes
up, it will continue from this state.
8.3.3.1
If the Fail-Safe Clock Monitor is enabled, a clock failure
will force the CCP to be clocked from the internal
oscillator clock source, which may have a different
clock frequency than the primary clock.
See Section 3.0 “Clock Sources” for additional
details.
8.3.4
Any Reset will force all ports to Input mode and the
CCP registers to their Reset states.

Configure the PWM pin (RC5/CCP1) as an input
by setting the TRISC<5> bit.
Set the PWM period by loading the PR2 register.
Configure the CCP module for the PWM mode
by loading the CCP1CON register with the
appropriate values.
Set the PWM duty cycle by loading the CCPR1L
register and CCP1CON<5:4> bits.
Configure and start TMR2:
• Clear the TMR2 interrupt flag bit by clearing
