1-4 Using the LSIU160
•
Supports SCRIPTS:
– Includes 8 Kbytes RAM for SCRIPTS instruction storage
– Supports multithreaded I/O algorithms in SCSI SCRIPTS with
fast I/O context switching
– Handles phase mismatches in SCRIPTS without interrupting the
system processor
– Supports Load/Store SCRIPTS instructions without use of PCI
cycles
•
Supports 31 levels of SCSI synchronous offset in the Single
Transition (ST) mode and 62 levels in the DT mode
