IMPORTANT
Notes on Address-Match Interrupt:
• Do not single-step an address where an address-match interrupt occurs.
• When using an address-match interrupt, do not check the box of "Enable the Address Match
Interrupt Break Function" in the MCU tab of the Init dialog box. When not using an address-match
interrupt, check the box.
• When you use address-match breaks, if a low reset is input during a user program execution, a debug
monitor program (about 100 cycles) is executed after a reset is released. Take note that it has effects
on the user program execution time and the result of a trace.
Notes on 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 target 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 out properly.).
(1) Single stepping
(2) Setting a software breakpoint
(3) Setting a hardware breakpoint
(4) Executing COME
Notes on Reset Vector Area:
• For a reset vector area, memory of the emulator is always selected regardless of the setting of the
EMEM dialog box. Therefore when setting a 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 memory window etc.
•A reset vector area can be changed only when a program is stopped. When a program is executed,
the area can not be changed.
