The following sections describe how the LSISAS1068 implements these
commands.
The LSISAS1068 ignores this command as a slave and never generates
it as a master.
The LSISAS1068 ignores this command as a slave and never generates
it as a master.
The I/O Read command reads data from an agent mapped in the I/O
address space. When decoding I/O commands, the LSISAS1068
decodes the lower 32 address bits and ignores the upper 32 address
bits. The LSISAS1068 supports this command when operating in either
the PCI or PCI-X bus mode.
The I/O Write command writes data to an agent mapped in the I/O
address space. When decoding I/O commands, the LSISAS1068
decodes the lower 32 address bits and ignores the upper 32 address
bits. The LSISAS1068 supports this command when operating in either
the PCI or PCI-X bus mode.
The LSISAS1068 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
LSISAS1068 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
