3.2.4
Power Supplies for 82562EZ(EX) PLC Implementations
The 82562EZ(EX) PLC device uses a single 3.3 V power supply. The 3.3 V supply must provide
approximately 90 mA current for full speed operation. Standby power must be furnished in order to
wake up from powerdown.
3.2.5
82562EZ(EX) Device Test Capability
The device contains an XOR test tree mechanism for simple board tests. Details of the XOR tree
operation are contained in the
82562ET LAN on Motherboard Design Guide.

Designing with the 82547GI(EI) Gigabit Ethernet Controller
This section provides design guidelines specific to the 82547GI(EI) controller.
3.3.1
82547GI(EI) Ethernet Controller LAN Disable Guidelines
The 82547GI(EI) Controller has a LAN_DISABLE# function that is present on FLSH_SO ball P9.
This pin can be connected to a GPIO pin on the ICH5 component to allow the BIOS to disable the
Ethernet port (see
If the serial FLASH interface is populated, make sure the FLASH
serial output pin does not interfere with this function.
