interrupts in sinusoidal pwm

[gedza]

I would like to ask how the other negative half cycle is produced and if the interrupts are used to load values to ccpr1l or if it is used to change from positive to negative half cycle of the sine wave.

The question is not clear - at least to me.

you can use full wave rectifier.. if i have understand correctly

SPWM also the output is '0' and '1', like PWM. Not much difficult on negative cycle.
