mapping. Accesses to this address range will send back the content of the Flash cell (by

default FFFFh, blank value when the device is delivered)

2 Accesses to the area will send back the value 009Bh.

Modules structure

The IFLASH module is composed by a bank (Bank 0) of 128 Kbyte of Program Memory

divided in 6 sectors (B0F0...B0F5). Bank 0 contains also a reserved sector named Test-

Flash. The Addresses from 0x08 0000 to 0x08 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 4: Flash modules sectorization (Read operations)), and when accessed in

write or erase mode (Table 5: Flash modules sectorization (Write operations or with

ROMS1=’1’ or BootStrap mode)): note that with this second mapping, the first four banks

are remapped into code segment 1 (same as obtained setting bit ROMS1 in SYSCON

register).
