2.7 GPIO (General Purpose Input / Output)
20 GPIO pins (16 channels without ACC and Ground) are provided by the Vortex86DX2 for
general usage in the system. All GPIO pins are independent and can be configured as inputs or
outputs, with or without pull-up/pull-down resistors.
However, VDX2-6518 only offers 8 channels of GPIO, GPIO Port 3, for you to use. These
channels are also occupied by onboard SPI flash disk. If you enable SPI flash disk in the CMOS
setting, you will not be able to use any GPIO channel.
Here is register information of GPIO Port 3 for your reference.
Port 6
Data Register: 7BH
Direction Register: 9BH
