[Note]
For unused input ports or unused input/output ports, if the corresponding pins are configured as high-impedance inputs
and left open, the supply current may become excessively large. Therefore, it is recommended to configure those pins as
either inputs with a pull-down resistor/pull-up resistor or outputs.
