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
monitor.
• The 64 KB allocated to the debug monitor cannot be used.
• The below areas cannot be set for the debug monitor.
(1) MCU internal resources (ROM/RAM/SFR area)
(2) DRAM area or multiplex area
(3) Interrupt vector area
• It is not possible to view or set the content of the specified area. Even on the dump window or
in the reverse assemble area of the program/source windows, the content of this area is not
displayed correctly though it can be displayed.
(2) Processor Mode
• Set the target MCU to the processor mode.
• To set the single-chip mode or memory expansion mode, the CNVSS pin used with MCU status
must be "L". MCU status indicates pin level of the target system.
•To set the microprocessor mode, the CNVSS pin used with MCU status must be "H".
• To set the memory expansion mode or microprocessor mode, the RDY* and HOLD* pins used
with MCU status must be "H".
•When the target system is not connected, all modes are available.
(3) Emulation Memory Allocation
• The 4MB memory mounted in the PC7501 can be allocated out.
•When the single chip mode and memory expansion mode are set by specifying the processor mode,
ROM area is automatically allocated to the internal Flash ROM of MCU. Therefore, it is not
necessary to deliberately specify the emulation memory as expansion area in order to allocate
the ROM area.
• Except for the SFR, RAM, ROM and internally reserved areas, all areas other than the set area
are externally accessible.
• MCU internal resources are automatically selected for SFR, RAM and ROM areas regardless
of settings.
• 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
memory size (4 MB).
•Do not set unusable areas for memory allocation.
•Emulator main unit's memory is automatically selected as a reset vector area regardless of
settings.
IMPORTANT
Notes on Reset Vector Area:
• For a reset vector area, memory of the emulator is always selected regardless of the setting of
EMEM dialog. Therefore when setting the 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.
