The mechanism of inserting Short Open Windows has to be enabled/configured with the bits SOWCONF. The
configuration allows to insert a maximum of three consecutive Short Open Windows. Each Trigger of the Short
Open Window will increase a SOW counter, if the SOW counter exceeds the maximum configured value a reset
will be generated. The SOW counter value is reset to 0 by a normal Trigger.
