3. I/O Register Address
3.1 How to Find the I/O Address
The Plug&Play BIOS will assign a proper I/O address to every PCI-1002 card
in the power-on stage. The IDs of PCI-1002 are as follows:
• Vendor ID
• Device ID
We provide the following necessary functions:
1. P1002_DriverInit(&wBoard)
This function can detect how many PCI-1002 cards are in the system. The
function is implemented based on the PCI Plug & Play mechanism-1. It will
find all PCI-TMC12 cards installed in this system & save all their resources
in the library.
• wBoard=1
• wBoard=2
2. P1002_GetConfigAddressSpace(wBoardNo, *wBase, *wIrq, *wPLX)
Use this function to save resources of all PCI-1002 installed in this
system. Then the application program can control all functions of PCI-
1002 directly.
• wBoardNo=0 to N
• wBase
• wIrq
• wPLX
