(a) 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).
