Management (OSPM) to achieve the most efficient power management possible. The RTL8100C(L) does not
support CardBus mode as the RTL8139C does. In addition to the ACPI feature, the RTL8100C(L) also supports
remote wake-up (including AMD Magic Packet, LinkChg, and Microsoft® wake-up frame) in both ACPI and APM
environments. The RTL8100C(L) is capable of performing an internal reset through the application of auxiliary
power. When auxiliary power is applied and the main power remains off, the RTL8100C(L) is ready and waiting for
the Magic Packet or Link Change to wake the system up. Also, the LWAKE pin provides 4 different output signals
including active high, active low, positive pulse, and negative pulse. The versatility of the RTL8100C(L) LWAKE
pin provides motherboards with Wake-On-LAN (WOL) functionality. The RTL8100C(L) also supports Analog
Auto-Power-down, that is, the analog part of the RTL8100C(L) can be shut down temporarily according to
user requirements or when the RTL8100C(L) is in a power down state with the wakeup function disabled. In
addition, when the analog part is shut down and the IsolateB pin is low (i.e. the main power is off), then both the
analog and digital parts stop functioning and the power consumption of the RTL8100C(L) will be negligible.
The RTL8100C(L) also supports an auxiliary power auto-detect function and will auto-configure related bits
of their own PCI power management registers in PCI configuration space.
