Cautions On Compatibility Of Card-Pci; Wake On Lan Signal - Epson SCE8720C Series Hardware Manual

A.3.3 Cautions on compatibility of CARD-PCI
It is recommended that signal inputs of PWSW#, PME0# and PME1# are set to low or
high impedance for compatibility with other CARD-PCIs (so that other cards can also
use the same main circuit). Also, STANDBY# signal is driven with open drain with
SCE8720C, but with other cards, it is driven HIGH/LOW at 3.3V. Therefore design the
circuit to support both, as shown in Figure A.7 and A.8.
A.3.4 Wake on LAN signal
PME0# signal is used for Wake on LAN. With PCI version 2.2, this signal is assigned to
A19 pin of the PCI option connector. However, SCE8720C's PCI is version 2.1, so do not
connect PME0# signal to the PCI connector. For Wake on LAN using PME0# signal, use
another connector. (There are connectors specified as "semi-standard".)
