2-4 Functional Description
2.1.1.3 Memory Space
The PCI specification defines memory space as a contiguous 64-bit
memory address that is shared by all system resources, including the
LSI53C896.
Base Address Register One (MEMORY) determines which
1 Kbyte memory area this device occupies. Each SCSI function uses a
8 Kbyte SCRIPTS RAM memory space.
Base Address Register Two
(SCRIPTS RAM) determines the 8 Kbyte memory area the SCRIPTS
RAM occupies.
2.1.2 PCI Bus Commands and Functions Supported
Bus commands indicate to the target the type of transaction the master
is requesting. Bus commands are encoded on the C_BE[3:0]/ lines
during the address phase. PCI bus commands and encoding types
appear in
Table 2.1 .
