TMS320F280023: GPIO mux configuration

Part Number: TMS320F280023


Hello,

I have simple question about GPIO Mux in 280023.

Typically, when we use the GPIO as SCI communication, it can be selected as GPIO 29 (SCIA_TX) and GPIO 28 (SCIA_RX).

Is it possible to select as GPIO 29 (SCIA_TX) and GPIO 17 (SCIA_RX) for SCI communcation? Is there a specific sequence or it just depends on mux configuration?

    Hi,

    Thanks for your question!

    You can use any combination of SCIA_RX and SCIA_TX pins for SCI communication. The GPIOs chosen does not matter. What matters is that they are both for the same SCI module. For example SCIA_RX should not go with SCIB_TX. As long as you keep the same SCI module (SCIA for example) you can use any of the GPIOs.

    Regards,
