This directive initiates the timer specified by ${.:/params[0]/name}. If the
timer is running, it is automatically canceled before being initiated. The
timer is scheduled to fire after an interval of clock ticks has passed
specified by ${.:/params[1]/name}. When the timer fires, the timer service
routine ${.:/params[2]/name} will be invoked with the argument
${.:/params[3]/name} in the context of the clock tick ${/glossary/isr:/term}.
