IMPORTANT
Notes on EMEM Dialog Box:
Observe the following when setting up EMEM dialog box of the emulator debugger.
(1) Debug Monitor Bank Address
When "E0" is specified, 64 KB of area starting from E00000h 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 memory expansion mode, pins RDY* and HOLD* used with MCU status must be "H".
When the user system is not connected, all modes are available.
Notes on the Watchdog Function:
When using the watchdog function, check the box of “Debug the program using the Watchdog Timer” in the
MCU tab of the Init dialog box. When not using the watchdog function, do not check the box.
If the reset circuit of the user system has a watchdog timer, disable it when using the emulator.
Notes on Debugging in CPU Rewrite Mode:
To debug a program in CPU rewrite mode, check the box “Debug the program using the CPU Rewrite Mode” in
the MCU tab of the Init dialog box. When you do not debug a program in CPU rewrite mode, uncheck the box.
When you debug a program in CPU rewrite mode, the block 0 area (FFF000h--FFFFFFh) must not be rewritten.
Otherwise, the emulator will be out of control.
When debugging in CPU rewrite mode is enabled, you cannot use the following functions.
(1) Setting an address match breakpoint
(2) Setting a software breakpoint to the internal ROM area
(3) Executing COME to the internal ROM area
Do not use the following functions to the rewrite control program area (from setting CPU rewrite mode select
bit to releasing it). If any of these are used, malfunctions may occur (e.g. The emulator cannot shift to CPU
rewrite mode or contents of ROM cannot be read our properly.).
(1) Single stepping
(2) Setting a software breakpoint
(3) Setting a hardware breakpoint
(4) Executing COME
