GENERAL DESCRIPTION  
The Z5380 SCSI (Small Computer System Interface) con-  
troller is designed to implement the SCSI protocol as  
defined by the ANSI X3.131-1986 standard, and is fully  
compatible with the industry standard 5380. It is capable  
of operating both as a Target and as an Initiator. Special  
high-current open-drain outputs enable the Z5380 to di-  
rectly interface to, and drive, the SCSI bus. The Z5380 has  
the necessary interface hook-ups which allows the system  
CPU to communicate with it like any other peripheral  
device. The CPU can read from, or write to, the SCSI  
registers which are addressed as standard or memory-  
mapped I/Os (Figure 1).  
detects a bus condition that requires attention. It also  
supports arbitration and reselection. The Z5380 has the  
proper hand-shake signals to support normal and block  
mode DMA operations with most DMA controllers avail-  
able (Figure 2).  
Notes:  
All Signals with a preceding front slash, "/", are active Low, e.g.,  
B//W (WORD is active Low); /B/W (BYTE is active Low, only).
