If Enable Bit is set the device
will be switched in active
mode. If Enable Bit is cleared
device go into standby mode
and all bits are cleared. After
power-on reset device starts in
standby mode.
If Reset Bit is set both status
registers will be cleared after
rising edge of CSN input.
This bit defines in combination
with the over-current recovery
bit (Input Register 1) the duty
cycle in over-current condition
of an activated driver.
If this bit is set the
microcontroller has to clear the
status register after
undervoltage/overvoltage
event to enable the outputs.
Depending on combination of
bit 18 and 19 the current
image (1/10.000) of the
selected HS-output will be
multi-plexed to the CM output:

HS-driver of OUT1 is only
selected if HS-driver OUT1 is
switched on and HS-driver
OUT6 is not activated.

A broken VCC-or SPI-connection of
the L9950 can be detected by the
microcontroller, because all 24 bits
low or high is not a valid frame.

overvoltage
In case of an overvoltage or
undervoltage event the
corresponding bit is set and the
outputs are deactivated. If VS
voltage recovers to normal
operating conditions outputs are
reactivated automatically (if Bit 20 of
status register 0 is not set).

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.
This bit is for information purpose
only. It can be used for a thermal
management by the microcontroller
to avoid a thermal shutdown.

Not Ready Bit
After switching the device from
standby mode to active mode an
internal timer is started to allow
chargepump to settle before the
outputs can be activated. This bit is
cleared automatically after start up
time has finished. Since this bit is
controlled by internal clock it can be
used for synchonizing testing
events (e.g. measuring filter times).
