Inverse of dead band observed in PWM, STM8S003F3

[vindhyachal]

1. I have written below code for PWM generation for STM8S003F3. Two pwm pins are used inverted with dead time.

2. But I observed this graph on CRO of two pins is this. I was expecting one pin to turn off before another turn on i.e deabband.. But reverse is happening here.

More I increase deadband it has reverse effect. What I am doing wrong here?
