Protection functions
The reaction to the warning is freely adjustable. All setting options for configurable
errors are available.
The default setting is "Warning". That means: upon reaching the pre-warning tem-
perature, bit 2 is set in
mask also bit 7 in the status word.
pn06 defines how the reference level for generating the overtemperature warning
is determined:

If one of the heatsink temperatures is higher than the comparison value,
the warning becomes active. If all heatsink temperatures are lower than
the comparison value minus the hysteresis (5 °C), the warning is reset.

If one of the heatsink temperatures is closer to its associated shutdown
threshold than pn07, the warning becomes active. The warning will be
reset if all heatsink temperatures are outside the range of
