An4013 "STM32 cross-series timer overview" possible errors

Uwe Bonnes

Hello,

I think following things in 2.4 Timer output compare mode are wrong:

3d) Enable the capture / compare output by writing CCxE in CCMRx register.

should read

Enable the capture / compare output by writing CCxE in CCERx register.

and

CCx update rate = CK_CNT / TIMx_CCRx

should read

CCx update rate = CK_CNT / TIMx_ARR

You're right regarding the first point. I will highlight this to be fixed in the next release of the application note.

Regarding the CCx update rate, I will further check this point and update you ASAP.
