(3) Reset vector
A reset vector includes the jump instruction for the debug monitor program.
[How to secure areas]
It is not necessary to secure this area intentionally. When downloading a program, however, the debugger rewrites
the reset vector in accordance with the following cases. If the rewritten pattern does not match the following cases,
the debugger generates an error (F0C34 when using the ID850QB).
(a) When two nop instructions are placed in succession from address 0
(b) When two 0xFFFF are successively placed from address 0 (already erased device)
(c) The jr instruction is placed at address 0 (when using CA850)
(d) mov32 and jmp are placed in succession from address 0 (when using IAR compiler ICCV850)
(e) The jump instruction for the debug monitor program is placed at address 0
0x6 jmp [reg1]
