SUS_STAT#
B18
O CMOS
3.3V Suspend/3.3V
Indicates imminent suspend operation; used to notify LPC devices.
SUS_S3#
A15
O CMOS
3.3V Suspend/3.3V
Indicates system is in Suspend to RAM state. Active low output. An
inverted copy of SUS_S3# on the Carrier Board may be used to
enable the non-standby power on a typical ATX supply.
SUS_S4#
A18
O CMOS
3.3V Suspend/3.3V
Indicates system is in Suspend to Disk state. Active low output.
SUS_S5#
A24
O CMOS
3.3V Suspend/3.3V
Indicates system is in Soft Off state.
WAKE0#
B66
I CMOS
3.3V Suspend/3.3V
PU 1K TO 3V3_DU
PCI Express wake up signal.
WAKE1#
B67
I CMOS
3.3V Suspend/3.3V
PU 10K TO 3V3_DU
NC PU 10 K TO 3V3_DU
General purpose wake up signal. May be used to implement wake-up
on PS2 keyboard or mouse activity.
BATLOW#
A27
I CMOS
3.3V Suspend/ 3.3V
PU 8.2K TO 3V3_DU
Indicates that external battery is low.
This port provides a battery-low signal to the Module for orderly
transitioning to power saving or power cut-off ACPI modes.
LID#
A103
I OD CMOS
3.3V Suspend/12V
LID switch. Low active signal used by the ACPI operating system for a LID switch.
SLEEP#
B103
I OD CMOS
3.3V Suspend/12V
PU 10K TO 3V3_DU
Sleep button. Low active signal used by the ACPI operating system to bring the
system to sleep state or to wake it up again.
THRM#
B35
I CMOS
3.3V / 3.3V
PU 10K TO 3V3
Input from off-Module temp sensor indicating an over-temp situation.
THRMTRIP#
A35
O CMOS
3.3V / 3.3V
PU 10K TO 3V3
Active low output indicating that the CPU has entered thermal shutdown.
SMB_CK
B13
I/O OD CMOS 3.3V Suspend/3.3V
PU 2.2K TO 3V3_DU_EC
NC PU 4.7K TO 3V3_DU
System Management Bus bidirectional clock line.
SMB_DAT
B14
I/O OD CMOS 3.3V Suspend/3.3V
PU 2.2K TO 3V3_DU_EC
NC PU 4.7K TO 3V3_DU
System Management Bus bidirectional data line.
SMB_ALERT#
B15
I CMOS
3.3V Suspend/3.3V
System Management Bus Alert – active low input can be used to
generate an SMI# (System Management Interrupt) or to wake the system.
