undefined, causing the power supply current to increase while the port remains in input mode.
Furthermore, by considering a possibility that the contents of the direction registers may change due to noise

periodically reset in software, for the increased reliability of the program.

After setting for input mode, connect every pin to VSS via a resistor (pull-down);
or after setting for output mode, leave these pins open.
Connect to VCC via a resistor (pulled high) by setting the corresponding
direction bit in the PD4 register for CSi (i = 1 to 3) to 0 (input mode) and
the CSi bit in the CSR register to 0 (chip select disabled).
