Figure 9-38. Peripheral Mode: External Master Writes
9.5.13 Contention Resolution on External Bus
When the MPC533 is in slave mode, external master access to the MPC533 internal bus can
be terminated with relinquish and retry in order to allow a pending internal-to-external
access to be executed. The RETRY signal functions as an output that signals the external
master to release the bus ownership and retry the access after one clock.
