Hi @baji,

You can use one of these timers: API, RTI (both configurable in the CPMU) or TIM in the output compare mode.

For example, this is API's selectable interrupt periods:

You can refer to the attached example, it utilizes TIM and API.

It is an S12ZVL example, but all the modules are very similar on MM9Z1.

Regards,

Daniel
