Add input to previous value of output, if rising edge of trigger port
This block has one Integer input "u", one Boolean input "trigger", an optional Boolean input "reset", an optional Integer input "set", and an Integer output "y". The optional inputs can be activated with the "use_reset" and "use_set" flags, respectively.
The input "u" is added to the previous value of the output "y" if the "trigger" port has a rising edge. At the start of the simulation "y = y_start".
If the "reset" port is enabled, then the output "y" is reset to "set" or to "y_start" (if the "set" port is not enabled), whenever the "reset" port has a rising edge.
The usage is demonstrated, e.g., in example Modelica.Blocks.Examples.IntegerNetwork1.
