4.2.9
In SBC Fail-Safe Mode, all voltage regulators are OFF and the transceivers are in Wake-Capable Mode. The Limp
Home output is active.
Conditions to enter the SBC Fail-Safe Mode are:
•

In case of
and will go back to SBC Restart Mode.
In case of a wake-up event, the SBC will go to SBC Restart Mode (not in case of
shutdown), storing the wake-up event and resetting the Watchdog trigger failure counter. The first SPI output data
when going to SBC Normal Mode will always indicate the reason for the SBC Fail-Safe Mode.
4.2.10
If the Test pin is connected to GND (Config 0 active) during powering-up, the SBC enters SBC Software
Development Mode. SBC Software Development Mode is a super set of the other modes so it is possible to use
all the modes of the SBC with the following difference. In SBC Software Development Mode, no reset is generated
and
indicated by the INT output (reset bit). The SBC Fail-Safe Mode or SBC Restart Mode are not reached in case of
wrong Watchdog trigger but the other reasons to enter these modes are still valid.
4.2.11
In this mode, the SBC is completely powered OFF and the microcontroller is supplied externally. The mode is
detected when
flow out of
maximum rating stated in
resistor.
Note: Please respect the absolute maximum ratings when the device is in SBC Factory Flash Mode.
