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.
23
Isolate Pin: Active low.
Used to isolate the RTL8110SC(L) from the PCI bus. The RTL8110SC(L) 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 PMEB asserts and ISOLATEB is low.
