SETUP FOR PWM OPERATION
The following steps should be taken when configuring
the CCP module for PWM operation:
1.
Set the PWM period by writing to the PR2 register.
2.
Set the PWM duty cycle by writing to the
CCPR1L register and CCP1CON<5:4> bits.
3.
Make the CCP1 pin an output by clearing the
TRISC<2> bit.
4.
Set the TMR2 prescale value and enable Timer2
by writing to T2CON.
5.
Configure the CCP1 module for PWM operation.
