Does STM32U5 series supports 1us hardware timer ?

I am looking for maximum timer resolution supported in STM32U5 series MCU's.

Basically whether I can configure or use hardware timer as 100us.

Any input or documentation on this would be a great help.

Thanks!!

Interrupting at 1 MHz is not a sensible approach to any problem.

The TIM have resolution into the nano-seconds (6.25 ns).

I'd imagine there's a Reference Manual describing the hardware implementation, and a cook-book of related examples.

Every timer in every STM32 model may be setup according to your needs.
