I need to generate deadtime of top and bottom PWM CH1 and CH1N about 1.5us. I set deadtime 190 and it has 1.5us deadtime, but I dont understand... I need you :loudly_crying_face:

This doesn't help.
You need to consult reference manual Section 17.4.18: TIM1 and TIM8 break and dead-time register (TIMx_BDTR) for delay calculation.

What is your timer clock speed? 1.5us over 190 ticks is about 125 MHz. Seems reasonable.
