External Bus Interface
9.5.2.3
The general case of single beat transfers assumes that the external memory has a 32-bit port size. The
MPC561/MPC563 provides an effective mechanism for interfacing with 16-bit and 8-bit port size
memories, allowing transfers to these devices when they are controlled by the internal memory controller.
In this case, the MPC561/MPC563 attempts to initiate a transfer as in the normal case. If the bus interface
receives a small port size (16 or 8 bits) indication before the transfer acknowledge to the first beat (through
the internal memory controller), the MCU initiates successive transactions until the completion of the data
transfer. Note that all the transactions initiated to complete the data transfer are considered to be part of an
atomic transaction, so the MCU does not allow other unrelated master accesses or bus arbitration to
intervene between the transfers. If any of the transactions except the first is re-tried during an access to a
small port, then a machine-check exception is generated to the RCPU.
