PCI LOCAL BUS CONFIGURATION SPACE REGISTERS
The PCI local bus configuration space registers are responsible for setting up the device’s operating
environment in the PCI local bus. The pre-defined operating parameters of the device are read by the PCI bus
plug-and-play auto-configuration manager in the operating system. After the PCI bus has collected all data
from every device/card on the bus, it defines and downloads the memory mapping information to each device/
card about their individual operation memory address location and conditions. The operating memory mapped
address location is downloaded into the Base Address Register (BAR) register, 0x10. The plug-and-play auto
configuration feature is only available when an external 93C46 EEPROM is used. The EEPROM contains the
device vendor and sub-vendor data required by the auto-configuration setup.
