Set-up for PWM Operation
Sleep Operation
Effects of a Reset
The following steps configure the CCP module for PWM operation:
1.
2.
3.
4.
5.
When the device is placed in sleep, Timer2 will not increment, and the state of the module will
not change. If the CCP pin is driving a value, it will continue to drive that value. When the device
wakes-up, it will continue from this state.
The CCP module is off.
Establish the PWM period by writing to the PR2 register.
Establish the PWM duty cycle by writing to the DCxB9:DCxB0 bits.
Make the CCPx pin an output by clearing the appropriate TRIS bit.
Establish the TMR2 prescale value and enable Timer2 by writing to T2CON.
Configure the CCP module for PWM operation.
