Notes:
1. ‘VDD’ is the voltage of the applicable power domain for each pin (selected by the corresponding GPn_PWR_DOM register).
2. Pull-up / pull-down resistance only applies when enabled using the GPn_PULL registers.
3. Pull-up / pull-down resistors are disabled when the GPIO pin is tri-stated.
4. Pull-up / pull-down resistance may change with the applicable power domain (as selected by GPn_PWR_DOM).
