If set to `true(1)' then Zero Suppression mode is enabled
Zero Suppression mode tells whether intervals with all
current counters equal to zero shall be stored in the history
log or not. If enabled, once a faulty interval is found, its
current register content including a zero suppressed interval
counter will be stored in the history log. The additional
counter specifies how many fault free intervals have preceded
the faulty one. In such way, history for a larger measurement
period can be logged than would otherwise be possible
