19.5.2.1.2 Outbound Address Translation
Figure 19-55 shows an example of XL Bus Initiator Window configurations. Overlapping the inbound
memory window (MCF548x Memory) and the outbound translation window is not supported and can
cause unpredictable behavior.
Figure 19-55 does not show the configuration mechanism.
