Internal Flash memory

Modules structure
The IFLASH module is composed of two banks. Bank 0 contains 384 Kbyte of program
memory divided in 10 sectors. Bank 0 contains also a reserved sector named test-Flash.
Bank 1 contains 128 Kbyte of program memory or parameter divided in two sectors
(64 Kbyte each).
The XFLASH module is composed of two banks as well. Bank 2 contains 192 Kbyte of
program memory divided in three sectors. Bank 3 contains 128 Kbyte of program memory
or parameter divided in two sectors (64 Kbyte 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 (Table 3), and when accessed in write or erase mode (Table 2): note that with this
second mapping, the first three banks are remapped into code segment 1 (same as
obtained when setting bit ROMS1 in SYSCON register).
