    Hi, I haven't understand a question about gpio pins and it's double function.

Example: I want to use UART0 with on TX and RX signal (no control signal needed).

I can set RX and TX for UART operation a RTS and CTS as GPIO pins?

In reference manual this is not explained well in my opinion. In the CMX_USB_LITE example UART not configured the state of RTS/CTS for UART operation but I want to be sure if this solution function.

My proc is MCF52223 but I think there is the same in all coldfire procs

Best regards
