6.14.1 Software development mode
6.14 Test modes
The Software development mode is intended to support software developers in writing
and pretesting application software without having to work around watchdog triggering
and without unwanted jumps to Fail-safe mode.
In Software development mode the following events do not force a system reset:
However, in case of a watchdog trigger failure the reset source information is still provided
in the System Status register as if there was a real reset event.
The exclusion of watchdog related resets allows simplified software testing, because
possible problems in the watchdog triggering can be indicated by interrupts instead of
resets. The SDM bit does not affect the watchdog behavior in Standby and Sleep mode.
This allows the cyclic wake-up behavior to be evaluated during Standby and Sleep mode
of the SBC.
All transitions to Fail-safe mode are disabled. This allows working with an external
emulator that clamps the reset line LOW in debugging mode. A V1 undervoltage of more

SBC). Transitions from Start-up mode to Restart mode are still possible.
