Synchronous Buck Converter- ATTINY85

Hi,

I am working on a synchronous buck converter circuit being driven by PWM from Attiny85 to drive two logic level mosfets. I am trying to output the highest frequency PWM from the Attiny which i believe is around 32kHz when using the internal 8Mhz clock speed. The two PWM signals have to be inverted of each other with dead time between them. Just wondering how to approach programming the fast PWM & Dead time on the attiny using its registers, as i am fairly new to programming registers on microcontrollers and don't really understand how they work. I have the mosfets connected to pin 5 & 6 on the Attiny.

Thanks for the help.
