PC Card controller programming model

This section describes the PCI1221 PCI configuration registers that make up the 256-byte PCI configuration

header for each PCI1221 function. As noted, some bits are global in nature and should be accessed only

through function 0.

PCI configuration registers (functions 0 and 1)

The PCI1221 is a multifunction PCI device, and the PC Card controller is integrated as PCI functions 0 and 1.

The configuration header is compliant with the PCI specification as a CardBus bridge header and is PC 99

compliant as well. Table 15 shows the PCI configuration header, which includes both the predefined portion of

the configuration space and the user-definable registers.
