TMS320F280049: Pull up and AIOs

Hi Experts,

If a GPyPUD is enabled, the pull up register is still enabled after the peripheral is selected.
For example, when the pull up is enabled for GPIO0 and then EPWM1_A is select, the pull up resister is still workable?

Thank you for your kind clarification.
Best regards,

No, I don't.
But I would like to know if it is automatically cancel the pull up or user has to reset the setting.

Thank you very much.
Best regards,

All pull-ups disable on reset by default. The user has to manually enable.
