The OCREF_CLR works only when the signal(Final comp output) is high. In blanking window, final comp output is low, so TIM3_CH2 remains its initial value high.

When comp1 is in the stage of blanking, the output of comp1 is low, so TIM3_CH2 remains high. Only after the the stage of blanking, the output of comp1 (high), the OCREF goes to zero, then TIM3_CH2 pin goes low.

I set the INP voltage of comp1 higher than the INM voltage of comp1. The pwm is high (PWM1 mode,CNT<CCRT)

How to use OCREF_CLR (COMP1 AS OCREF_CLR),I found it not work correctly.(STM32G431C8t6).When comp1 is in blanking mode,the pwm is low(it should be high).

How to use COMP on STM32g431c8T6? I found it not work correctly. The pol is noninverted When INP(1.6V)<INM(2v),the out is high. Only INP=0, the out is low.

I use DAC sawtooh mode(STM32g431c8T6), Decrement mode.Does the value of DAC_DOR equal to the value of DAC_DHR ?

What is the relationship between the DAC_DOR register value and the DAC_DHR register value? I use STM32G431C8T6.

Does STM32g431c8t6 support DAC dual channel ?
