Comments
BATLOW#
S156 Battery low indication to Module.
Carrier to float the line in inactive state.
I OD
CMOS
1.8 to 5V
Standby/Sleep PU 10k
Driven by OD on Carrier
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
1.8Vsb / 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
1.8 to 5V
Standby/Sleep PU 10k
Driven by OD on Carrier.
CHARGING#
S151 Held low by Carrier during battery charging.
Carrier to float the line when charge is complete.
I OD
CMOS
1.8 to 5V
Standby/Sleep PU 10k
Driven by OD on Carrier.
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
Module must implement PU but actual
value is depended on particular Module
design. Driven by OD on Carrier
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
1.8 to 5V
Standby
PU 10k
Driven by OD on Carrier.
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
1.8 to 5V
Standby
PU 10k
Driven by OD on Carrier.
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
1.8 to 5V
Sleep
PU 10k
Driven by OD on Carrier.
