6.3.19 Inverting of Flags
(do.25...do.32)
In the second logic step a selection of the flags of the first logic step can be made.
The selection is done for each output separately, where one can choose between
no one and up to all 8 flags. According to Fig. 6.3.18 the weighting of the selected
flags is to be entered into do.33...do.40. If several flags shall be selected, the sum
is to be formed.
With the parameters do.25...do.32 each of the 8 flags (bit 0...7) from logic step 1
can be inverted separately. Through this function it is possible to set any chosen
flag as Non-flag. The parameter is bit-coded. According to Fig. 6.3.18 the weighting
of the switching conditions to be inverted must be entered in do.25...do.32. If several
flags shall be inverted, the sum is to be formed.

After the switching conditions are selected for each output, it can now be determined,
how these are linked. As a default all conditions are OR-operated, i.e. if one of the
selected conditions is met, the output switches. Another possibility is the AND-
operation, which is adjusted with do.41. AND-operation means, that all selected
condtions must be fulfilled before the output switches.
Parameter do.41 is bit-coded. The table under 6.3.20 shows the assignment.
