TMS320F28377S: resistor value for GPIO internal pull-up resistor

The Electrical Characteristics of TMS320F28377S data sheet shows as below, so it means the 120uA for pull-down and 150uA for pull-up?

Thanks

Hardy,

To elaborate further on the point, the 120uA and 150uA  values that you find in the datasheet are the pull currents provided by the GPIO passive pull structures.

External pull resistors providing this much current should be enough to bias the pins when the GPIO pulls are disabled.

However, if you are using an external pull resistor to oppose the GPIO pulls when they are enabled, the external resistor should be sized so that its pull current is a good deal greater than 120uA or 150uA.  The opposing pulls will act like a voltage divider.  For example, equal external and internal pull currents will result in a floating-pin voltage near VDDIO / 2.
