TMS320F28379D: Is it possible to change pin mux at run time in TMS320F28379D?

Part Number: TMS320F28379D

Hi,

    I would like to know is it possible to change pin mux at run time? Due to my wrong design, I want to change GPIO89 & GPIO90's pin mux between External memory interface pin and sci pin. Is it possible and is there anything to be careful?

Thank you for your time.

Jack

    Yes you can change pinmux during application. You have to be careful of application level glitches. For example if you have your pin as GPIO and driven low as output, when you switch it to Input with pull up enabled, you will get a level change. Things similar to that must be taken into account.
