Hey guys,

I am new to STM32 MCUs and i am looking for the maximum possible baud rate in synchronous USART mode for the STM32F031F4. For asynchronous mode this is clearly noted in the manual. For the synchronous mode, however, not. It is only mentioned, that the setup and hold time should be respected, which is 1/16 Bit time.. which i don't really get what that is. Can somebody explain to me what this means?

 

The manual is http://www.st.com/content/ccc/resource/technical/document/reference_manual/c2/f8/8a/f2/18/e6/43/96/DM00031936.pdf/files/… 

and the 1/16 Bit time is mentioned on page 715.

 

Thanks in advance!
