When using PWM on PIC16f877 we use CCPR1L and <4:5> of CCP1CON register.Then what is CCPR1H?Why isn't it used?
 

Hi coshcun

I remember it's used internally for double buffering to produce glitch-free PWM.
I need to look up the datasheet to confirm this!

Giri

Yes, I've confirmed this. :D During PWM mode it's a read only register!(For double buffer)
