Hi 

How can we use USART as UART port in STM32L431VCT6 micro controller

I am looking for connecting two STM32L4 micro controller with TX, RX and Ground lines.

Already UART port is being used for other purpose and have only USART port

regards

If you could share some thoughts what makes you use USART instead of SPI.

Well, that's simple - all the SPIs are used for other purposes... ;)

Exactly, and it's not even a good implementation of synchronous serial, which would minimally have two independent clocks. And lacks any SDLC/HDLC support.

I'm sure the peripheral could be used for other assorted SERDES type implementations, along with SPI, but still a bit of a hack.
