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.
