PWM & Timer2

[bananasiong]

Just a quick one, am I right that the PWM duty cycle will be updated after the next cycle of Timer2 get started if I modify CCPRxH:CCPRxL before Timer2 match PR2? So anyhow I have to waste one cycle of Timer2 if any modification on the duty cycle.

Thanks

Yes, the duty cycle takes effect at the next PR2 match. Think of it as staying one PWM cycle ahead.

Thanks. If the duty cycle is modified, won't the PWM of the current cycle get affected?

Nope, it's buffered. Nice glitchless PWM on the PICs.

OIC, thanks for that
