9.5.11
The MPC561/MPC563 bus architecture requires assertion of TA from an external device to signal that the
bus cycle is complete. TA is not asserted in the following cases:
External circuitry can provide TEA when no device responds by asserting TA within an appropriate period
of time after the MPC561/MPC563 initiates the bus cycle (it can be the internal bus monitor). This allows
the cycle to terminate and the processor to enter exception-processing for the error condition (each one of
the internal masters causes an internal interrupt under this situation). To properly control termination of a
bus cycle for a bus error, TEA must be asserted at the same time or before TA is asserted. TEA should be
negated before the second rising edge after it was sampled as asserted to avoid the detection of an error for
the next initiated bus cycle. TEA is an open drain pin that allows the “wired-or” of any different sources
of error generation.
9.5.11.1
When an external device asserts the RETRY signal during a bus cycle, the MPC561/MPC563 enters a
sequence in which it terminates the current transaction, relinquishes the ownership of the bus, and retries
the cycle using the same address, address attributes, and data (in the case of a write cycle).

termination of a transfer. As seen in this figure, in the case when the internal arbiter is enabled, the
MPC561/MPC563 negates BB and asserts BG in the clock cycle following the retry detection. This allows
any external master to gain bus ownership. In the next clock cycle, a normal arbitration procedure occurs
again. As shown in the figure, the external master did not use the bus, so the MPC561/MPC563 initiates a
new transfer with the same address and attributes as before.

with BB. One clock cycle later, the normal arbitration procedure occurs again.
