Hi, everybody!

Is it possible to synchronize Timers A and B used in PWM-Mode?

Frequency is 20 KHz.

In my Application there is a little disturbing time-offset between both output-signals.

After Reset both the timers are on, so if you do not disable either of the timers in your code and you do not change the Timer clock (i.e. it is Fcpu/4, the reset value) for both the timers then the PWM signal for both will be exactly synchronised provided the compare register values are the same.
