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.
