The LSISAS1064 uses the Memory Read command to read data from
an agent mapped in the memory address space. The target can perform
an anticipatory read if such a read produces no side effects. The
LSISAS1064 supports this command when operating in the PCI bus
mode.
The Memory Read Dword command reads up to a single Dword of data
from an agent mapped in the memory address space and can only be
initiated as a 32-bit transaction. The target can perform an anticipatory
read if such a read produces no side effects. The LSISAS1064 supports
this command when operating in the PCI-X bus mode.
The Memory Write command writes data to an agent mapped in the
memory address space. The target assumes responsibility for data
coherency when it returns “ready.” The LSISAS1064 supports this
command when operating in either the PCI or PCI-X bus mode.
This command is reserved for future implementations of the PCI
specification. The LSISAS1064 never generates this command as a
master. When a slave, the LSISAS1064 supports this command using
the Memory Read Block command.

The Configuration Read command reads the configuration space of a
device. The LSISAS1064 never generates this command as a master,
but does respond to it as a slave. A device on the PCI bus selects the
