Datasheet
5. Pin Descriptions
The following signal type codes are used in the tables:
I: Input.
O: Output
T/S: Tri-State bi-directional input/output pin.
S/T/S: Sustained Tri-State.
O/D: Open Drain.

Power Management Event: Open drain, active low.
Used to request a change in the current power management state
and/or to indicate that a power management event has occurred.
Isolate Pin: Active low.
Used to isolate the RTL8110S from the PCI bus. The RTL8110S
will not drive its PCI outputs (excluding PME#) and will not
sample its PCI input (including PCIRSTB and PCICLK) as long
as the Isolate pin is asserted.
LAN WAKE-UP Signal (When CardB_En=0, bit2 Config3):
This signal is used to inform the motherboard to execute the
wake-up process. The motherboard must support Wake-On-LAN
(WOL). There are 4 choices of output that may be asserted from
the LANWAKE pin (active high, active low, positive pulse, and
negative pulse). We can configure the LANWAKE output via two
CONFIG bits: LWACT(Config1.4) and LWPTN(Config4.2).

The default output is an active high signal. Once a PME event is
received, the LANWAKE and PMEB assert at the same time
when the LWPME (bit4, CONFIG4) is set to 0. If the LWPME is
set to 1, the LANWAKE asserts only when the PMEB asserts and
ISOLATEB is low.
