TERMINATION OF UNUSED PINS
Table 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.
