Securing of user resources and setting of security ID

MINICUBE2 uses the user memory spaces (shaded portions in Figure 4-29) to implement communication with
the target device, or each debug functions.
other areas are used for each debug function used.
and secure these spaces in the user program or using the compiler options.
