(3)16-bit SCSI mode setting(Differential type, 16-bit SCSI)
Set setting terminal CN7 7-8 to enable or disable the 16-bit SCSI mode(See Table 8). When the 16-bit SCSI mode is enabled, all data bus (DB00 to DB15, DBP0 toDBP1) can be effective.
When the Differential type 16-bit SCSI HDD is used as 8-bit SCSI device, this setting must be open.
