20K, PU
V3P3S
Serial ATA 0 General Purpose:
This is an input pin which can
be configured as an interlock
switch or as a general purpose
I/O depending on the
platform. When used as an
interlock switch status
indication, this signal is driven
to 0 to indicate that the switch
is closed and to 1 to indicate
that the switch is open. If the
SATA_GP0 interface is not
used, the signals can be used
as GPIO Port 15.

V3P3S
Serial ATA LED: This is an
open-collector output pin
driven during SATA command
activity. It is to be connected
to external circuitry that can
provide the current to drive a
platform LED. When active,
the LED is on. When tri-
stated, the LED is off. An
external pull-up resistor is
required. If the SATA_LEDN
interface is not used, the
signals can be used as GPIO
Port 16.
