2.5.15. Drive Strength Requirement for GPIO Input Pins
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.
