TMS320F28069: Methods to override the internal pulls during reset

Part Number: TMS320F28069

1.Except PWM pins,the pullups on other GPIO pins are enabled upon reset.Can I change this default behaviour of the MCU.

2.What is the strong PD resistor value to override the internal pull up during reset.

    Jagbir,

    1. You cannot change the default behavior.
    2. A pull down resistor depends on the application.
      1. If its going on TRSTn then 2.2Kohms is recommended to ensure absolutely no glitching occurs
      2. Other pins typically a 4.7K ohm resistor is recommended.
