2 PWM response • 0: Push/pull output
Push/pull mode should be used if you need defined high/low levels for a
rapid change. This is used with a low load especially if "highside" mode
cannot move the output to low fast enough during a low status. With
push/pull, the output is switched to ground with low active and to
voltage with high active.
•1: Highside output
In highside mode, the output switched to low remains in a state of
uncertainty between ground and voltage. The load has to "pull" itself to
ground. In highside mode, the switch is only made to high level active.
