    4.2.3 Bus signal drive conditions SCSI devices drive signals of the SCSI bus. The types of SCSI devices are summarized in the following table, showing the signals that they can drive for each operating phase of the interface. There are two kinds of signal driving methods, OR tied and NON-OR tied, as shown in Table 4.2. During an interface operating sequence.
