2 PWM response l 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.
l 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.
