MPC8548 Memory Map
The monitor can boot from either the soldered flash (Bank 1, default) or the socketed PLCC
device. Based on the configuration header (see page2-8) either the socketed device or sol-
dered flash is mapped to the boot bank at FFF8,000016, see Fig.4-2. Information on particu-
lar portions of the memory map can be found in later sections of this manual, see Table 4 -2.
