21150
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 this is a write transaction,
within the time frame specified by the master timeout value; otherwise, the transaction is discarded
from the 21150 buffers.

Target Disconnect

The 21150 returns a target disconnect to an initiator when one of the following conditions is met:
The 21150 hits an internal address boundary
The 21150 cannot accept any more write data
The 21150 has no more read data to deliver
See
Section 4.5.4
for a description of write address boundaries, and
of read address boundaries.
4.8.4.3
Target Abort
The 21150 returns a target abort to an initiator when one of the following conditions is met:
The 21150 is returning a target abort from the intended target.
The 21150 is unable to obtain delayed read data from the target or to deliver delayed write data
to the target after 2
When the 21150 returns a target abort to the initiator, it sets the signaled target abort bit in the status
register corresponding to the initiator interface.
