Pin Signal / Function Pin Type Signal Description Device/Connection
S148 LID#
O OD 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. J51 LS to 3.3V
(CMOS 1.8 to
5V)
(Feature Connector)
S149 SLEEP#
O OD
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.
J51 LS to 3.3V
(CMOS 1.8 to
5V)
level sensitive. Should be de-bounced on the
Module.
(Feature Connector)
S150 VIN_PWR_BAD#
O OD
Power bad indication from CB. 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.
Board Controller
STM32
(VDD_IN)
S151 CHARGING#
O OD
Held low by CB during battery charging. Carrier
to float the line when charge is complete. not connected on
CB
(CMOS 1.8 to
5V)
S152 CHARGER_PRSNT#
O OD
Held low by CB if DC input for battery charger is
present. not connected on
CB
(CMOS 1.8 to
5V)
S153 CARRIER_STBY# I (CMOS 1.8V)
The module drives this signal low when the
system is in a standby power state. Board Controller
STM32
S154 CARRIER_PWR_ON I (CMOS 1.8V)
Carrier Board circuits (apart from power
management and power path circuits) are not
powered up until the module asserts the
CARRIER_PWR_ON signal.
Board Controller
STM32
S155 FORCE_RECOV#
O OD (CMOS
1.8V)
Low on this pin allows non-protected segments
of Module boot device to be re-written / restored
from an external USB host on Module USB0.
The module USB0 operates in Client Mode when
in the force recovery function is invoked. Pulled
high on the Module. For SOCs that do not
implement a USB based force recovery functions,
then a low on the module FORCE_RECOV# pin
may invoke the SOC native force recovery mode
– such as over a serial port. For x86 systems this
signal may be used to load BIOS defaults. Pulled
up on module. Driven by OD part on carrier.
J44
S156 BATLOW#
O OD
Battery low indication to module. Carrier to float
the line in inactive state. not connected on
CB
(CMOS 1.8 to
5V)
S157 TEST#
O OD
Held low by carrier to Invoke module vendor
specific test functions.
Test point TP313
(CMOS 1.8 to
5V)
