TIM1 Complementary output with dead-time insertion not correct ?

[Jerry Yung]

Hello , now I debug about Complementary output with dead-time feature of TIM1 CH1 and CH1N, I set deadtime 5us ,and TIM1's period 50us , then I get scope via oscilloscope ,

but the scope is not what I expect , refer to below , In fact DT1 == 2*DT2 ,

I expect DT1 == DT2 , so I don't know where is not correct ?

THANK YOU !
