Notes On Emem Dialog Box; Note On Software Break - Renesas M30830T-RPD-E User Manual

Notes on EMEM Dialog Box:

Observe the following when setting up EMEM dialog box of the emulator debugger.
(1) Debug Monitor Bank Address
• When "F0" is specified, 64 KB of area starting from F00000h are allocated for use by the debug
• The 64 KB allocated to the debug monitor cannot be used.
• The below areas cannot be set for the debug monitor.
• It is not possible to view or set the content of the specified area. Even on the dump window or
(2) Processor Mode
• Set the target MCU to processor mode.
• To set the single-chip mode and memory expansion mode, pin CNVSS used with MCU status
• To set microprocessor mode, pin CNVSS used with MCU status must be high.
• To set the memory expansion mode and microprocessor mode, pins RDY* and HOLD* used
(3) Emulation Memory Allocation
• The 1.5MB memory mounted in the product can be allocated out.
• When the single chip mode or memory expansion mode is set by specifying processor mode,
• Except for the SFR, RAM, ROM and internally reserved areas, all areas other than the internal
• MCU internal resources are automatically selected as SFR and RAM areas regardless of
• Be careful that the specified areas do not overlap one another.
• Set memory allocation so that the total of the 4 length values does not exceed the emulation
• Do not set unusable areas for memory allocation.
• Emulation pod memory is automatically selected as reset vector area regardless of settings.

Note on Software Break:

• Software breaks generate break interruptions by forcibly inserting a BRK instruction "08h" instead
of a instruction code. Therefore, when referencing the result of a trace in bus mode, "08h" is
displayed for the instruction fetch address where a software break is set.
