Thanks a lot for the fast answer.
As I sad, I like to drive an DRV8305. This one needs 3 PWM signals which are synchronised (rising flank of high times starts at the same time and not displaced). For PWM channels in the same timer Group this is automaticly correct. But because I Need a second timer for the third PWM, I have to synchronize two timers.
Exactly, I like to set timer 3 with channel D2 and D3 as Master and Timer 4 channel D1 as Slave PWM.
Davidcane did something simmilar with PWM complementary outputs
And his solution was also the peripherial library.
