Appendix3:GPIO Instruction
MITX-6891 provides a five way input and a five way output programable interface. Input
and output of the interfaces are independent. In the GPIO interface, there are 12 Pin which are
link to 10 digital bits. This interface is generated by the onboard chip on PCI bus, and the bus
number is 0, device number is 18 and function number is 0. This interface is using the 3rd basic
address register.
According to PCI standard, the basic address are allocated by the BIOS
dynamically, and it is a MUST normally to obtain the basic address before program this
interface(if there are no other PCI expansion device, the basic address is: CC00H).
GPIO's interface debugging program is attached in the CD of the packinglist. Running the
GPIO executable file will start the GPIO debug program.
