after bkin is detected io state is not avaliable as presented in reference manual

[rpip.1]

i configure tim1 bkin. after bkin is triggered, tim1 2 3 output seems like high-z state.

my ossi bit is 0. MOE is cleared by trigger. according to reference i can set corresponding GPIO to high or low. but it doesn't work.

Hi @rpip.1​ ,

Which product are you using?

Besides to the reference manual, there is an application note which explains the break feature and provides examples for various possible configurations.

It is AN4277: Using STM32 device PWM shut-down features for motor control and digital power conversion.
