Problem with STM32F37 USART1 Clock Mux on PCLK2

Hello together,

I'm working with an STM32F37 MCU and have somme issues with the USART1 Clock Mux.

I enabled the Receiver Timeout Interrupt to detect the end of a Modbus message. With the HSI clock the interrupt occurs as expected. If I switch to the PCLK2 no interrupt will be triggered whilst the rest of the MCU is working fine.

Please see the picture below to get a clue of my clock configuration.

Thank you in advance for your support.

Regards

Phil
