PWM with BKIN

CKN
Visitor

Hello,

I want to use the Timer1 CH1 and CH1N of the STM32H563ZI with dead time generator and break input functionality. It should behave in that way that when the break input (BKIN) is triggered it should goes to a predigined idle state (for CH1 low and for CH1N goes high). After setting the configuration to PWM mode 1 in that way and run the program on oscilloscope I can observe that eg. when the CH1 is low, CH1N is high and the BKIN triggers, the CH1 keep being low, but the CH1N change it state to low for dead time period and again goes high as a predefined idle state. Is it normal behaviour of the timer that even when the output should be high when BKIN occure it is pulling down for dead time and after dead time it is enabling the idle states?
