About Digital I/O

The onboard digital I/O has 8 bits (DIO0~7). Each bit can be set to function as input or output
by software programming. In default, all pins are pulled high with +5V level (according to main
power). The BIOS default settings are 3 inputs and 5 outputs where all of these pins are set to
1.
