PWM1
PWM1 input.
This input signal can be used to control the drivers OUT1-OUT8 and
OUT11 by an external PWM signal.

Highside driver output 7,8,9,10.
The output is built by a highside switch and is intended for resistive
loads, hence the internal reverse diode from GND to the output is
missing. For ESD reason a diode to GND is present but the energy
which can be dissipated is limited. The highside driver is a power
DMOS transistor with an internal parasitic reverse diode from the
output to VS (bulk-drain-diode). The output is over-current and open
load protected.
