Description

Aux. Power Detect: This pin is used to notify the RTL8100B(L) of the

existence of Aux. power during initial power-on or a PCI reset.

This pin should be pulled high to the Aux. power 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

RTL8100B(L) assumes that no Aux. power exists.

The MA2-0 pins are switched to EESK, EEDI, EEDO in 93C46

programming or auto-load mode.
