8-bit CMOS tri-state I/O port.
Each bit can be set individually as either an input or output by P0DIR
register. A pull-up resistor for each bit can be selected individually by
P0PLU register.
Direct LED drive is available at output.
At reset, the input mode is selected and pull-up resistor is disabled
(high impedance).
