(default) attempts of the same delayed read transaction on the target bus, PI7C7100 asserts
P_SERR# if the primary SERR# enable bit is set (bit 8 of command register for secondary bus S1 or S2) and the delayed-
write-non-delivery bit is not set. The delayed-write-non-delivery bit is bit 5 of P_SERR# event disable register (offset 64h).
PI7C7100 will report system error. See Section 7.4 for a description of system error conditions.
4.8.4 Target Termination Initiated by PI7C7100
PI7C7100 can return a target retry, target disconnect, or target abort to an initiator for reasons other than detection of that
condition at the target interface.

ADVANCE INFORMATION
4.8.4.1 Target Retry
PI7C7100 returns a target retry to the initiator when it cannot accept write data or return read data as a result of internal
conditions. PI7C7100 returns a target retry to an initiator when any of the following conditions is met:
For delayed write transactions:
The transaction is being entered into the delayed transaction queue.
Transaction has already been entered into delayed transaction queue, but target response has not yet been
received.
Target response has been received but has not progressed to the head of the return queue.
The delayed transaction queue is full, and the transaction cannot be queued.
A transaction with the same address and command has been queued.
A locked sequence is being propagated across PI7C7100, and the write transaction is not a locked transaction.
The target bus is locked and the write transaction is a locked transaction.
Use more than 16 clocks to accept this transaction.
For delayed read transactions:
The transaction is being entered into the delayed transaction queue.
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 PI7C7100, and the read transaction is not a locked transaction.
PI7C7100 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.
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 PI7C7100, 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.
