    The advice?

    Check the chapter about timers in the processor documentation.

    Or look for sample code or application notes about how to use the processor timers.

    It isn't needed to use interrupts with the timers - it's possible to poll too. The main thing is that the timers ticks their time without caring about what other things happens.
