For posted write transactions:
TARGET DISCONNECT
PI7C8150A returns a target disconnect to an initiator when one of the following conditions
is met:
See Section 3.5.4 for a description of write address boundaries, and Section 3.6.3 for a
description of read address boundaries.
TARGET ABORT
PI7C8150A returns a target abort to an initiator when one of the following conditions is
met:
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 PI7C8150A, and the read transaction is
not a locked transaction.
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.
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 PI7C8150A, 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.
PI7C8150A hits an internal address boundary.
PI7C8150A cannot accept any more write data.
PI7C8150A has no more read data to deliver.
PI7C8150A is returning a target abort from the intended target.
