SCSI Commands
Completion Status
When a counter reaches the maximum, the counter is no longer incremented. If a
maximum value for the parameter size is reached, the count does NOT roll over and
continue counting. When any counter of a page reaches maximum, all counters of
that page are no longer incremented. A Log Select command can be issued for
pages 02h, 03h, and 32h with the PCR bit set to reset the accumulated values and to
allow counters to continue as normal. The DU bit of the affected parameter is also
reset to zero. The same effect can be achieved by a SCSI Bus Reset, Bus Device
Reset, or cartridge loading.
