OUT11 – HS on/off
If a bit is set the selected
output driver is switched on. If
the corresponding PWM
enable bit is set (Input Register
1) the driver is only activated if
PWM1 (PWM2) input signal is
high. The outputs of OUT1-
OUT6 are half bridges. If the
bits of HS- and LS-driver of the
same half bridge are set, the
internal logic prevents that both
drivers of this output stage can
be switched on simultaneously
in order to avoid a high internal
current from VS to GND. In test
mode (CSN>7.5V) this bit
combinations are used to
multiplex internal signals to the
DO-output.

No error Bit
In case of an over-current event the
corresponding status bit is set and
the output driver is disabled. If the
over-current Recovery Enable bit is
set (Input Register 1) the output will
be automatically reactivated after a
delay time resulting in a PWM
modulated current with a
programmable duty cycle (Bit 21).
If the over-current recovery bit is not
set the microcontroller has to clear
the over-current bit (Reset Bit) to
reactivate the output driver.

Enable Bit
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.
Always 1
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.
