6.1 Overview
The SCRIPTS processor is initialized by setting and clearing bits in the
operating registers. This chapter lists the various registers used by the
LSI53C7XX/8XX/10XX family chips, grouped by function. The register
descriptions provide an overview of the aspects of chip operation that are
controlled in each register. The SCRIPTS processor also has a set of
PCI Configuration registers, but they are not described in this document
since they are initialized by the system, not by the SCSI driver program.
Full definitions of these registers, as well as the individual bits in the
operating registers, can be found in the chip technical manuals.
