ataSheProduct Features
w.D ■ Complies fully with Revision 2.1 of the PCI
w Local Bus Specification,
w ■ Complies fully with Revision 1.1 of the
PCI-to-PCI Bridge Architecture
mSpecification,
■ Complies fully with the Advanced
oConfiguration Power Interface (ACPI)
Specification
.c■ Complies fully with the PCI Power
Management Specification, Revision 1.01
U■ Implements delayed transactions for all PCI
configuration, I/O, and memory read
t4commands—up to three transactions
simultaneously in each direction
■ Allows 88 bytes of buffering (data and
eaddress) for posted memory write
commands in each direction—up to three
etransactions simultaneously in each
direction
h■ Allows 72 bytes of read data buffering in
each direction
S■ Provides concurrent primary and secondary
bus operation to isolate traffic
ta■ Provides five secondary clock outputs
— Low skew, permitting direct drive of
aoption slots
— Individual clock control through
.Dconfiguration space
■ Provides arbitration support for four
secondary bus devices
— A programmable 2-level arbiter
— Hardware disable control, permitting use
of an external arbiter
■ Provides enhanced address decoding
— A 32-bit I/O address range
— A 32-bit memory-mapped I/O address
range
— A 64-bit prefetchable memory address
range
— ISA-aware mode for legacy support in
the first 64 KB of I/O address range
— VGA addressing and VGA palette
snooping support
■ Supports PCI transaction forwarding for the
following commands
— All I/O and memory commands
— Type 1 to Type 1 configuration
commands
— Type 1 to Type 0 configuration
commands (downstream only)
— All Type 1 to special cycle configuration
commands
■ Includes downstream lock support
■ Supports both 5 V and 3.3 V signaling
environments
w1. 21152–AB and later revisions only. The 21152–AA does not implement this feature.
