Limit counter (L4UFCNT) is intended for applications where positive and/or negative flanks on
a binary signal need to be counted.
The limit counter provides four independent limits to be checked against the accumulated
counted value. The four limit reach indication outputs can be utilized to initiate proceeding
actions. The output indicators remain high until the reset of the function.
It is also possible to initiate the counter from a non-zero value by resetting the function to the
wanted initial value provided as a setting.
If applicable, the counter can be set to stop or rollover to zero and continue counting after
reaching the maximum count value. The steady overflow output flag indicates the next count
