How to generate Half-bridge pwm signals with dead-time using coldfire v1

Hello guys,

Is there a way I can generate a half-bridge pwm signals with dead-time using coldfire v1 ?

I'm using the mcf51jm128

I need to generate two complementary pwm signals with a dead-time in between the up and down of each others.

Frequency around 60-100khz would be enough.

It could also be done setting a duty cycle under 50% and being able to delay one pwm from another.

You'll be able to find context schematics attached.

Any help would be great,

Thanks already !
