STM32C092 USART1 clocking issue

[PGump.1]

Hi all,

I’m looking at a STM32C092 for some UART stuff. The data sheet has USART1 on an independent clock. Using MX I select USART1 as Asynchronous and MX calculates the rate according to the independent clock as expected,

However, when I select USART1 as Synchronous MX calculates the bit rate according to the APB clock. I don’t have a device to test it on.

Is MX right or wrong?

Thanks in advance

Hello ​@PGump.1 ;

 

Which STM32CubeMX version are you using?

Could you please share more details about the issue: IOC file, screenshot issue…?

 

Thank you
