Modules structure
The IFlash module is composed by 2 banks: (Bank 0) contains 384 Kbytes of Program
Memory divided in 10 sectors (B0F0...B0F7), Bank 0 contains also a reserved sector named
Test-Flash. Bank 1 contains 128 Kbytes of Program Memory or Parameter divided in two
sectors (B1F0, B1F1, 64 Kbytes each). Addresses from 0x0E 0000 to 0x0E FFFF are
reserved for the Control Register Interface and other internal service memory space used
by the Flash Program/Erase controller.
The following tables show the memory mapping of the Flash when it is accessed in read
mode
or erase mode
the first four banks are remapped into code segment 1 (same as obtained setting bit
ROMS1 in SYSCON register).
