STM32U575 TIM1 clock output on TIM_CH1 pin is unable to be higher than 250kHz

STM32U575 TIM1 output TIM_CH1 clock is unable to be higher than 250kHz in up, toggle mode. The system clock is set to 160MHz. I am looking for the output clock higher than 1.6MHz.

Is this possible? Thanks.

Yes, should be easy to get pins at those rates.

Problem is that you're trying to use interrupts, and those have realistic ceilings in the 100's of KHz, before saturating the processor in a lot of useless / busy work.

Bingo! I have it works. Yes, by removing the interrupt option, the clock output thrilled.

Thank you very much.
