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 input. Active low input. Edge triggered
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
Reset output from module to Carrier Board. Active low. Issued by module chipset and may result
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
SUS_S4#
A18
Indicates system is in Suspend to Disk state. Active low output
O 3.3 VSB
Not supported
SUS_S5#
A24
Indicates system is in Soft Off state
O 3.3 VSB
