Notes On Access Prohibited Area; Notes On Stack Area; Notes On Reset Vector Area - Renesas M30830T-RPD-E User Manual

Notes on Access Prohibited Area:

• The emulator control register (000020h - 00003Fh) in the SFR is read and write-protected. When
this register is accessed, emulator control cannot be utilized.
• With this product, address FFFFFFh cannot be read or written in correctly.

Notes on Stack Area:

• With this product, a maximum 20 bytes of the user stack is consumed as work area.
• If the user stack does not have enough area, do not use areas which cannot be used as stack (SFR
area, RAM area which stores data, or ROM area) as work area. Using areas like this is a cause of
user program crashes and destabilized emulator control. Therefore, ensure the +20 byte maximum
capacity used by the user program as the user stack area.
• With this product, the interrupt stack pointer (ISP) is set to 0500h and used as stack area after the
reset is released.

Notes on Reset Vector Area:

• For a reset vector area, memory of the emulation pod is always selected regardless of the setting
of EMEM dialog box. Therefore when setting microprocessor mode, to use a ROM of the target
system etc. as an area including a reset vector area, set a reset vector using a dump window etc.
• The reset vector area can be changed only when a program is stopped. When a program is executed,
the area can not be changed.
