TMS320F280049: GPIO24 and GPIO32 pullup

Part Number: TMS320F280049

Hello Champs,

In F280049 controlCARD, GPIO24 and GPIO32 has been both pulled up with 56K resistor.

Would you please kindly suggest whether this pull-up is enough or not? Thanks!

Best Regards,

Linda

    Hi Linda,

    This will mostly depend on the application use for the pin. Are you using this a boot mode pin?

    Regards,

    Hello Kris,

    GPIO24 and GPIO32 will be used as boot mode pin at power-up for internal flash boot and will be switched to GPIO when user codes run.

    Would you please kindly recommend the pull-up and pull-down resistors value for this kind of application? Thanks!

    Best Regards,

    Linda
