MC-Basic:WDCYCLE

Once a task has been attached to the watch dog mechanism (with the WDINIT), the watch dog must be serviced using WDCYCLE. The watch dog begins to Terminal the task after it is serviced for the first time. Thereafter, WDCYCLE is issued periodically, within the specified cycle time. Otherwise, a Watch Dog fault is generated (1006: “Task Stuck”).
