PWRBTN# B12 Power button to bring system out of S5 (soft off),
active on falling edge.
I 3.3VSB PU 10k
3.3VSB
SYS_RESET# B49
Reset button input. Active low request for module
to reset and reboot. May be falling edge sensitive.
For situations when SYS_RESET# is not able to
reestablish control of the system, PWR_OK or a
power cycle may be used.
I 3.3VSB PU 10k
3.3VSB
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
3.3VSB
PWR_OK B24
Power OK from main power supply. A high value
indicates that the power is good. This signal can be
used to hold off Module startup to allow carrier
based FPGAs or other configurable devices time to
be programmed.
I 3.3V
PU 100k
3.3VSB
SUS_STAT# B18 Indicates imminent suspend operation; used to
notify LPC devices.
O
3.3VSB
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
3.3VSB
SUS_S4# A18
Indicates system is in Suspend to Disk state.
Active low output.
O
3.3VSB
SUS_S5#
A24
Indicates system is in Soft Off state.

implement wake-up on PS/2 keyboard or mouse
activity.
