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

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).
