2.5.15. Drive Strength Requirement for GPIO Input Pins

Each GPIO input pin with programmable bus-hold or programmable pull-up feature turned on requires 1 mA of drive strength. The connected output buffer must provide a minimum of 1 mA to the pin.

If an output buffer drives two input pins, the output buffer must provide 2 mA to the input pins. Increase the drive strength current according to the number of input pins the output buffer drives.

If you connect an output buffer to multiple input pins and one of the input pins has programmable bus-hold or programmable pull-up feature enabled, you must turn on the same programmable feature on all of the other input pins.
