P140 Not connected S141 LCD_BKLT_PWM (Display backlight PWM
control)
P141 Not connected S142 Not connected
P142 GND S143 GND
P143 Not connected S144 RSVD / EDP_HPD (Reserved for future
eDP Hot Plug Detect pin)
P144 Not connected S145 WDT_TIME_OUT# (Watchdog Timer
Output)
P145 Not connected S146 PCIE_WAKE (PCIe wake up interrupt to
host – common to PCIe; links A, B, C –
pulled up or terminated on Module)
P146 Not connected S147 VDD_RTC (Low current RTC circuit backup
power – 3.0V nominal. May be sourced from
a Carrier based Lithium cell or Super Cap.
See
Section 7.3 RTC Voltage Rail
of the
SMARC specification for an important
safety note on the implementation of lithium
backup batteries.)
P147 VDD_IN (Module power input voltage -
5V) S148 LID# (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 inactive state. Active low, level
sensitive. De-bounced on the Module
Pulled up on Module.
Driven by OD part on Carrier.)
P148 VDD_IN (Module power input voltage -
5V) S149 SLEEP# (Sleep indicator from Carrier
board; sourced from user Sleep button or
Carrier logic. Carrier to float the line in
inactive state. Active low, level sensitive; de-
bounced on the Module.
Pulled up on Module.
Driven by OD part on Carrier.)
P149 VDD_IN (Module power input voltage -
5V) S150 VIN_PWR_BAD# (Power bad indication
from Carrier board. Module
and Carrier power supplies (other than
Module and Carrier power supervisory
circuits)
is not
enabled while this signal is
held low by the Carrier.
Pulled up on Module.
Driven by OD part on Carrier.)
P150 VDD_IN (Module power input voltage -
5V) S151 CHARGING# (Held low by Carrier during
battery charging. Carrier to float the line
when charge is complete. Pulled up on
Module. Driven by OD part on Carrier.)
P151 VDD_IN (Module power input voltage -
5V) S152 CHARGER_PRSNT# (Held low by Carrier if
DC input for battery charger is present.
Pulled up on Module. Driven by OD part on
Carrier.)
P152 VDD_IN (Module power input voltage -
5V) S153 CARRIER_STBY# (The Module drives this
signal low when the system is in a standby
power state)
