I want to change the minimum pulse of PWM

Hi JerryChang.

I understand that 48Mhz is the maximum CLK.

What is the minimum unit of Duty Cycle(%)?
I want to know the PWM resolution.

hello k-irisa,

duty cycle is measured in percentage. the percentage of duty cycle specifically describes the percentage of time a digital signal is on over an interval or period of time.
your use-case of 0.05% duty cycle is a very short period, how about consider using a GPIO interrupt.

Hi JerryChang.

It turned out that it is difficult to achieve a duty cycle of 0.05% with PWM alone.
I would like to consider another plan.
Thank you for your advice.
