OUT1 – HS on/off
If a bit is set the selected output driver is switched on. If the corresponding PWM
enable bit is set 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.

the device enters standby mode and all bits are cleared.
