Table 1-3 shows methods of terminating the unused pins.
Note:
It is recommended to set the unused input ports and input/output ports to the inputs with pull-down resistors/pull-up
resistors or the output mode since the supply current may become excessively large if the pins are left open in the high
impedance input setting.
