System Memory

One on-board Flash ROM (U11) is used in the system. The Am29LV160DB-XX device contains 16 Mbits 
of non-volatile storage (1 Mbyte x 16), giving a total of 2 Mbytes of Flash memory. The lower 256 Kbytes 
are used to store the M5253EVBE dBUG debugger/monitor firmware that is pre-programmed into the 
Flash during factory testing.

The MCF5253 processor has 128 Kbytes of internal SRAM organized as 2 banks of 64 Kbytes. The 
SRAM can be used for either data or instruction space.
