4.3 EPROM/EEPROM Interface
Symbol

Type
I
Pin No
50
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.
