Description
CAN (Controller Area Network) TX output for CAN Bus channel 0.
In order to connect a CAN controller device to the Qseven module's CAN
bus it is necessary to add transceiver hardware to the carrier board.
RX input for CAN Bus channel 0. In order to connect a CAN controller
device to the Qseven module's CAN bus it is necessary to add transceiver
hardware to the carrier board.
Description
High active input for the Qseven® module indicates that all power rails
located on the carrier board are ready for use.
Power Button: Low active power button input. This signal is triggered on
the falling edge.
Description
Reset button input. This input may be driven active low by an external
circuitry to reset the Qseven module.
Battery low input. This signal may be driven active low by external
circuitry to signal that the system battery is low or may be used to signal
some other external battery management event.
External system wake event. This may be driven active low by external
circuitry to signal an external wake-up event.
S3 State: This signal shuts off power to all runtime system components
that are not maintained during S3 (Suspend to Ram), S4 or S5 states.
The signal SUS_S3# is necessary in order to support the optional S3 cold
power state.
S5 State: This signal indicates S4 or S5 (Soft Off) state.
Sleep button. Low active signal used by the ACPI operating system to
transition the system into sleep state or to wake it up again. This signal is
triggered on falling edge.
LID button. Low active signal used by the ACPI operating system to
detect a LID switch and to bring system into sleep state or to wake it up
again.
Open/Close state may be software configurable.
