mcf54415 mcPWM prescaler

anyone had mcPWM prescaler working ?

I tried in several different sequences, but all works only with prescaler at 0, otherwise, submodule counter is not increasing.

Would be nice to know if this prescaler ever worked, if there is a sure-working example around,

thanks

Hi,

so, i have seen several similar cases where prescaler was not working, i can post the solution for my case.

Seems not declared in any place in the RM, but if you use a logic as INIT and VAL0 = 0, all unsigned, as i was using for simplicity, prescaler will not work. To have it working, signed logic must be used.
