Notes On Emem Dialog; Note On S/W Break - Renesas Emulation Pod for M16C/80 Group MCUs M30803T-RPD-E User Manual

Notes on EMEM Dialog:

Observe the following when setting up EMEM dialog 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 the processor mode.
• To set the single-chip mode and memory expansion mode, the CNVSS pin used with MCU
• To set the microprocessor mode, the CNVSS pin used with MCU status must be "H".
• To set the memory expansion mode and microprocessor mode, the RDY* and HOLD* pins used
(3) Emulation Memory Allocation
• The 1.5MB memory mounted in the product can be allocated out.
• When the single chip mode and memory expansion mode are set by specifying the processor mode,
• Except for the SFR, RAM, ROM and internally reserved areas, all areas other than the set area
• MCU internal resources are automatically selected as SFR and RAM areas regardless of
• Even when "00" is specified as the expansion area, internally reserved areas (006400h -
• 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 S/W Break:

• S/W 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 S/W break is set.
