lists the standard PCI header registers that are supported. Registers whose initial values
Default value is dependent on device revision.
BAR3’s read back value is FFFFFC00h after writing FFFFFFFFh. BAR4’s read back value
is FFFFFF01h after writing FFFFFFFFh.
The Subsystem Vendor ID and Subsystem Device ID can be configured by the serial
EEPROM. if no EEPROM is connected to LAN9420/LAN9420i, then the default values in
the table are used.
