EEPROM. After reload completed, this bit will be cleared
automatically.

2~0 OpMode These three bits are used to configure AN983B’s operation 111b
R/W
mode:
111b: Single Chip mode (Normal operation)
At this mode, AN983B is configured as single chip to provide
PCI to Ethernet controller.
100b: MAC-only mode
The AN983B is configured as a MAC only controller, it provide
standard MII interface to link to the external PHY. The MII
interface pins are multiplexed with BootROM interface.
Others: For diagnostic purpose.
