Comments
BATLOW#
S156
Battery low indication to Module. Carrier to float
the line in inactive state.
I OD
CMOS
1.8V to 5V
Standby/
Sleep
PU 10K
Driven by OD on Carrier.
Pulled up on module.
CARRIER_PWR_ON
S154
Carrier Board circuits (apart from power
management and power path circuits) should not
be powered up until the Module asserts the
CARRIER_PWR_ON signal.
O
CMOS
1.8V
Standby
On x86 designs this pin should utilize
a standby related power signal i.e.
RSM_RST# or SLP_A# signal.
CARRIER_STBY#
S153
The Module shall drive this signal low when the
system is in a standby power state.
O
CMOS
1.8V
Standby
On x86 designs this pin should utilize
the SUS_S3# signal.
CHARGER_PRSNT#
S152
Held low by Carrier if DC input for battery charger
is present.
I OD
CMOS
1.8V to 5V
Standby/
Sleep
PU 10K
Driven by OD on Carrier.
Pulled up on module.
CHARGING#
S151
Held low by Carrier during battery charging.
Carrier to float the line when charge is complete.
I OD
CMOS
1.8V to 5V
Standby/
Sleep
PU 10K
Driven by OD on Carrier.
Pulled up on module.
VIN_PWR_BAD#
S150
Power bad indication from Carrier Board. Module
and Carrier power supplies (other than Module
and Carrier power supervisory circuits) shall not
be enabled while this signal is held low by the
Carrier.
I OD
CMOS
VDD_IN
PU 10K
Driven by OD on Carrier
Module must implement PU but
actual value is depended on particular
module design.
SLEEP#
S149
Sleep indicator from Carrier Board. May be
sourced from user Sleep button or Carrier logic.
Carrier to float the line in in-active state. Active
low, level sensitive. Should be de-bounced on
the Module.
I OD
CMOS
1.8V to 5V
Standby
PU 10K
Driven by OD on Carrier.
Pulled up on module.
LID#
S148
Lid open/close indication to Module. Low
indicates lid closure (which system may use to
initiate a sleep state). Carrier to float the line in
in-active state. Active low, level sensitive. Should
be de-bounced on the Module.
I OD
CMOS
1.8V to 5V
Standby
PU 10K
Driven by OD on Carrier.
Pulled up on module.
POWER_BTN#
P128
Power-button input from Carrier Board. Carrier to
float the line in in-active state. Active low, level
sensitive. Should be debounced on the Module.
I OD
CMOS
1.8V to 5V
Standby
PU 10K
Driven by OD on Carrier.
Pulled up on module.
RESET_OUT#
P126
General purpose reset output to Carrier board.
