If the result of the function block operation is "TRUE" these bits indicate which bit positions
have to be RESET in the monitor function trigger status register.
Note: If all trigger qualify bits in "trg_set" and "trg reset" are set to zero, none of the
function trigger bits will be changed (filtering and range checking).
Example:
If the trigger qualify bits are setup as shown below and the result of the function block
check is TRUE the function trigger bit T0 will be set and T1, T2 and T3 will be reset in the
monitor function trigger status register.

Pre Qualify Counter
Each time the examined label matches the condition defined in the function definition word
the pre qualify counter will be decremented by one. If the counter reaches zero the function
block operation is TRUE. The pre qualify counter should be initialized to 1.

counter. This value will be loaded into the pre qualify counter location each time the pre
qualify counter has been decremented to zero. The pre qualify counter reg should be
initialized to 1.
