    Hi.

    I'm a new user of the TMS320F28335 DSC.

    If I use the MCBSP as SPI, may I use the MFSRx and the MCLKRx pin as GPIO or not?

    Another question: when I use the SPI interface (pin GPIO54 to GPIO57) but I don't need the SPISIMOA, may I use it as GPIO54 pin?

    Thanks a lot for your answers

    Igor

      Igor,

      You may use any pins which are not required by your SPI application as GPIO.

      And may I use the MFSRx pin and MCLKRx pin as GPIO if I use the McBSP as SPI?

      Thanks

      Regards
