Registers Format
The detailed descriptions of the registers format are specified in this
chapter. This information is quite useful for the programmers who
wish to handle the card by low-level programming. However, we
suggest user have to understand more about the PCI interface then
start any low-level programming. In addition, the contents of this
chapter can help users understand how to use software driver to
manipulate this card.
3.1
PCI PnP Registers
This PCI card functions as a 32-bit PCI target device to any master on
the PCI bus. There are three types of registers: PCI Configuration
Registers (PCR), Local Configuration Registers (LCR) and PCI-6308
registers.
The PCR, which is compliant to the PCI-bus specifications, is
initialized and controlled by the plug & play (PnP) PCI BIOS. User‘s
can study the PCI BIOS specification to understand the operation of
the PCR. Please contact with PCISIG to acquire the specifications of
the PCI interface.
The PCI bus controller PCI-9050 is provided by PLX technology Inc.
(www.plxtech.com). For more detailed information of LCR, please visit
PLX technology’s web site to download relative information. It is not
necessary for users to understand the details of the LCR if you use
the software library. The PCI PnP BIOS assigns the base address of
the LCR. The assigned address is located at offset 14h of PCR.
The PCI-6308 registers are shown in the next section. The base
address, which is also assigned by the PCI PnP BIOS, is located at
