Aux. Power Detect.

This pin is used to notify the RTL8100C(L) of the existence of Aux.

power (only during initial power-on). This pin should be pulled high

to the auxiliary power (5VPM or 3VAUX) via a resistor to detect the

Aux. power. Doing so will enable wakeup support from ACPI D3

cold or APM power-down. If this pin is not pulled high, the

RTL8100C(L) assumes that no auxiliary power exists.

EEDI: After Aux. Power On Detection is complete; EEDI is enabled

to support EEPROM auto-load operation.
