ADVANCE INFORMATION

July 31, 2003 – Revision 1.031
!
!
The read request has already been queued, but read data is not yet available.
Data has been read from target, but it is not yet at head of the read data queue or a
posted write transaction precedes it.
!
!
The delayed transaction queue is full, and the transaction cannot be queued.
A delayed read request with the same address and bus command has already been
queued.
!
A locked sequence is being propagated across PI7C8150B, and the read transaction is
not a locked transaction.
!
!
!
For posted write transactions:
!
The posted write data buffer does not have enough space for address and at least one
DWORD of write data.
!
A locked sequence is being propagated across PI7C8150B, and the write transaction is
not a locked transaction.
!
When a target retry is returned to the initiator of a delayed transaction, the initiator
must repeat the transaction with the same address and bus command as well as the data
if it is a write transaction, within the time frame specified by the master timeout value.
Otherwise, the transaction is discarded from the buffers.
PI7C78150B is currently discarding previously pre-fetched read data.
The target bus is locked and the write transaction is a locked transaction.
Use more than 16 clocks to accept this transaction.
3.8.4.2
TARGET DISCONNECT
PI7C8150B returns a target disconnect to an initiator when one of the following conditions
is met:
!
PI7C8150B hits an internal address boundary.
!
PI7C8150B cannot accept any more write data.
!
PI7C8150B has no more read data to deliver.
See Section 3.5.4 for a description of write address boundaries, and Section 3.6.3 for a
description of read address boundaries.
3.8.4.3
TARGET ABORT
PI7C8150B returns a target abort to an initiator when one of the following conditions is
met:
