CTRL_OUTBV
PWM output 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.

PWM 1: period
Set parameters here for the total time for pulse duration
and pulse pause. The time should be selected as a factor
for the 20.83 ns basis.
Values below 25
ms are ignored. If the pulse duration is
higher or equal to the period, the DO output is set
permanently.
Value range: 1200 ... 8388607 (25
