PIN NO.
DESCRIPTION
STK_RSTB
I/PU
112
Sticky Reset Signal
A. Normal and MAC mode
Sticky_ResetB is a hardware reset signal which is
generated from auxiliary power circuit if motherboard
supports auxiliary power. So W89C841F can generate
PMEB from D3
(cold)
state to D0 state transition and
preserve PME context bits: PME_Status and
PME_Enable.
B. PHYceiver mode
This pin should be floating.
PWGD
I
111
Power Good
A. Normal and MAC mode
When PWGD = 1, W89C841F is put in normal
operation mode.
When PWGD = 0, it isolates any PCI input and has all
PCI outputs kept in high impedance state. The PCI bus
power can be off by operating system.
B. PHYceiver mode
This pin should be pulled to high.
PMEB
O/OD
122
Power Management Event
The PMEB signal indicates that a power management
event has occurred, i.e. there is a magic packet
received in suspend mode of host.
CLKRUNB
I/OD
113
Clock Run
CLKRUNB is used to request starting or speeding up
the PCI clock. It also indicates the PCI clock status.
W89C841F requests the central resource to start,
speed up, or maintain the PCICLK by the assertion of
CLKRUNB. For the central resource, CLKRUNB is an
S/T/S signal. The central resource is responsible for
maintaining CLKRUNB asserted and for driving it high
to deasserted state.
