Modules structure
The IFLASH module is composed by a bank (Bank 0) of 256 Kbyte of Program Memory
divided in 8 sectors (B0F0...B0F7). 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
write or erase mode
ROMS1=’1’ or BootStrap
are remapped into code segment 1 (same as obtained setting bit ROMS1 in SYSCON
register).
Table 5.
Table 6.
The table above refers to the configuration when bit ROMS1 of SYSCON register is set.
