Description
B12
PWRBTN#
I CMOS
Power button to bring system out of S5 (soft off), active on
rising edge.
B49
SYS_RESET#
I CMOS Reset button input. Active low input. System is held in
hardware reset while this input is low, and comes out of
reset upon release.
B50
CB_RESET#
O CMOS 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.
B24
PWR_OK
I CMOS
Power OK from main power supply. A high value indicates
that the power
B18 SUS_STAT#

suspend operation; used to notify LPC
devices.
A15
SUS_S3#
O CMOS
Indicates system is in Suspend to RAM state. Active low
output.
A18
SUS_S4#
O CMOS
Indicates system is in Suspend to Disk state. Active low
output.
A24 SUS_S5#
O CMOS
Indicates system is in Soft Off state. Also known as
