Notes on EMEM Dialog Box:

Observe the following when setting up EMEM dialog box of the emulator debugger.
(1) Debug Monitor Bank Address
• The default value of Debug Monitor Bank Address is "F0". To set single-chip mode or memory expansion
mode, internal flash memory is automatically allocated in E000h--FFFFh and FC0000h--FFFFFFh.
Therefore, change the Debug Monitor Bank Address to the area which does not start from "F0". The
specified value becomes effective after restarting the system.
• When "D0" is specified, 64 KB of area starting from D00000h are allocated for use by the debug monitor.
• The 64 KB allocated for 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) Multiplex area
3) Interrupt vector area
• It is not possible to view or set the content of the specified area. Even on the memory 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 a processor mode for the target MCU.
• To set single-chip mode or memory expansion mode, pin CNVSS used with MCU status must be "L".
MCU status indicates pin level of the user system.
• To set microprocessor mode, pin CNVSS used with MCU status must be "H".
• To set memory expansion mode or microprocessor mode, pins RDY# and HOLD# used with MCU status
must be "H".
• When the user system is not connected, all modes are available.
(3) Emulation Memory Allocation
• The memory mounted in the PC7501 can be allocated out.
• When single-chip mode or memory expansion mode is set as a processor mode, ROM area is
automatically allocated to the internal Flash ROM of an 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 a multiplex bus area and unusable areas for memory allocation.
• Emulator main unit's memory is automatically selected as a reset vector area regardless of settings.

Notes on Watchdog Function:

• When using the watchdog function, select the check box of "Debug the program using the Watchdog Timer" in
the MCU tab of the Init dialog box. When not using the watchdog function, clear the check box.
• If the reset circuit of the user system has a watchdog timer, disable it when using the emulator.
