I believe he was asking "What will the PWM be driving", such as a motor, LED, piezo, etc.ErnieM maybe you can tell how to calculate PWM frequency for your device?
My device here is a PIC12HV615, and the PWM frequency is set by the Timer2 compare feature: when timer 2 meets a value set in the PR2 register the period is complete, and the timer is reset.ErnieM maybe you can tell how to calculate PWM frequency for your device?
