BRIDGE ACTIONS FOR VARIOUS CYCLE TYPES
Initiator
Target
Response
Master on Primary
Target on Primary
PI7C7300D does not respond. It detects
this situation by decoding the address as
well as monitoring the P_DEVSEL# for
other fast and medium devices on the
Primary Port.
Master on Primary
Target on Secondary
PI7C7300D asserts P_DEVSEL#,
terminates the cycle normally if it is able
to be posted, otherwise return with a retry.
It then passes the cycle to the appropriate
port. When the cycle is complete on the
target port, it will wait for the initiator to
repeat the same cycle and end with normal
termination.
Master on Primary
Target not on Primary nor
Secondary Port
PI7C7300D does not respond and the
cycle will terminate as master abort.
Master on Secondary
Target on the same
Secondary Port
PI7C7300D does not respond.
Master on Secondary
Target on Primary or the
other Secondary Port
PI7C7300D asserts S1_DEVSEL# or
S2_DEVSEL#, terminates the cycle
normally if it is able to be posted,
otherwise returns with a retry. It then
passes the cycle to the appropriate port.
When cycle is complete on the target port,
it will wait for the initiator to repeat the
same cycle and end with normal
termination.
Master on Secondary
Target not on Primary nor
the other Secondary Port
PI7C7300D does not respond.
15.2
TRANSACTION ORDERING
To maintain data coherency and consistency, PI7C7300D complies with the ordering
rules put forth in the PCI Local Bus Specification, Rev 2.2. The following table
summarizes the ordering relationship of all the transactions through the bridge.
PMW - Posted write (either memory write or memory write & invalidate)
DRR - Delayed read request (all memory read, I/O read & configuration read)
DWR - Delayed write request (I/O write & configuration write, memory write to
certain location)
DRC - Delayed read completion (all memory read, I/O read & configuration read)
DWC - Delayed write completion (I/O write & configuration write, memory write
to ccertain location
Cycle type shown on each row is the subsequent cycle after the previous shown on the
column.
Can Row Pass Column?
