TPS65987D: GPIO12/13

Part Number: TPS65987D

Hi

I make TPS65987D FW by Application Customization Tool V.4.01.

Even if I assign any event to GPIO12 or 13, the pins are always High.

I use TPS65987-90 Evaluation Module.

Please tell me why I cannot use GPIO12 and 13?

    Hi Anderson,

    GPIO 12 and 13 are default to be SWD pins with an internal pull-up. During Power on reset, these pins will be high. If you do not have them configured as GPIOS, they will remain high. If they are configured as GPIOs, they should not remain high after booting. I would suggest double checking the configuration and making sure there is no pull-up on those pins.

    Thank you,
    Eric
