PWRBTN#
B12
Power button to bring system out of S5 (soft off), active on falling edge
Note: For proper detection, assert a pulse width of at least 16 ms.
I 3.3 VSB
PU 100 kΩ
3.3 VSB
SYS_
RESET#
B49
Reset button, active low, edge triggered input. System will not be held in hardware reset while
this input is kept low.
Note: For proper detection, assert a pulse width of at least 16 ms.
I 3.3 VSB
PU 10 kΩ
3.3 VSB
CB_RESET# B50
Active low reset output from module to Carrier Board. Issued by module chipset and may occur
from a low SYS_RESET# input, a low PWR_OK input, a VCC_12V power input that falls below the
minimum specification, a watchdog timeout, or may be initiated by the module software
O 3.3 V
PD 100 kΩ
PWR_OK
B24
Power OK from main power supply. A high value indicates that the power is good
I 3.3 V
Set by resistor divider to
accept 3.3V
SUS_STAT# B18
Indicates imminent suspend operation; used to notify LPC devices
O 3.3 VSB
SUS_S3#
A15
Indicates system is in Suspend to RAM state. Active-low output. An inverted copy of SUS_S3# on
the carrier board (also known as “PS_ON”) may be used to enable the non-standby power on a
typical ATX power supply
O 3.3 VSB PD 100 kΩ
SUS_S4#
A18
Indicates system is in Suspend to Disk state. Active low output
O 3.3 VSB PD 100 kΩ Not supported
SUS_S5#
A24
Indicates system is in Soft Off state
O 3.3 VSB PD 100 kΩ
WAKE0#
B66
PCI Express wake up signal
I 3.3 VSB
PU 1 kΩ
3.3 VSB
WAKE1#
B67
General purpose wake up signal. May be used to implement wake-up on PS/2 keyboard or
mouse activity
I 3.3 VSB
PU 10 kΩ
3.3 VSB
BATLOW#
A27
Battery low input. This signal may be driven low by external circuitry to signal that the system
battery is low, or may be used to signal some other external power-management event
I 3.3 VSB
PU 10 kΩ
