Always 1
A broken VCC-or SPI-
connection of the L9951 can
be detected by the
microcontroller, because all
16 bits low or high is not a
valid frame.
14
Not used
VS over-voltage
In case of an over-voltage or
undervoltage event the
corresponding bit is set and
the outputs are deactivated.
13
Not used
VS undervoltage
In case of an over-voltage or
undervoltage event the
corresponding bit is set and
the outputs are deactivated.
12
Not used
Thermal
shutdown
In case of an thermal
shutdown all outputs are
switched off. The
microcontroller has to clear
the TSD bit by setting the
reset bit to reactivate the
outputs.
11
Not used
Temperature
warning
This bit is for information
purpose only. It can be used
for a thermal management by
the microcontroller to avoid a
thermal shutdown.
