These 4 bytes contain the ID code word for the SC92031
These 4 bytes contain the ID code word for the chip. The chip will load the
contents of EEPROM into the corresponding location if the ID word is right,
otherwise, the chip will not proceed with the EEPROM autoload process.
PCI Maximum Latency Timer, PCI configuration space offset 3Fh.
PCI Minimum Grant Timer, PCI configuration space offset 3Eh.
Interrupt Pin
Interrupt Line Selection.
PCI Subsystem ID, PCI configuration space offset 2Eh-2Fh.
PCI Subsystem Vendor ID, PCI configuration space offset 2Ch-2Dh.
Reserved
Ethernet ID, After auto-load command or hardware reset, the chip loads
Ethernet ID to I/O registers.
Reserved
