Securement of memory space
The shaded portions in Figure 6-11 are the areas reserved for placing the debug monitor program, so user
programs or data cannot be allocated in these spaces. These spaces must be secured so as not to be
used by the user program. Moreover, this area must not be rewritten by the user program.
Setting of security ID and on-chip debug option byte
The security ID or on-chip debug option byte must be embedded in the area filled with yellow (0xC3 and
0xC4 to 0xCD) in Figure 6-11, to prevent the memory from being read by an unauthorized person.
