GPIO PU/PD resitor value on F2812

Hi,

What is the value of the pull up and pull down resistors on the F2812? I haven't found any information on the documentation... and can they be disabled via SW?

Thanks,

Maite

    Maite,

    The internal pullups/downs on F2812 are active circuits, not passive resistors.  There is no Ohms rating.  Rather, there are current ratings given in the datasheet, SPRS174O, p.93.  You can roughly think of these ratings as the amount of current needed to overpower the pullup/down and cause the pin to change logic level.

    On F281x devices, the internal pullups/downs cannot be disabled.

    Regards,

    David
