PWM highlight Timer

[Scipio]

Hello, I am new in STM32Cube. I try some test with PWM timer 4. It  works. I see the signal on oscilloscope. But why is not in clock configuration  highlighted the timer clock and I can not also change the clock source.

Best regards.

Which STM32?

In most STM32, if the respective APB divider is >1, the timer's clock frequency is fixed at APB frequency x2, so you can change it only by changing the APB clock frequency.
