IMPORTANT

Notes on Address-Match Interrupts:

•When you use the address-match interrupt function in a user program, uncheck "Enable the Address

Match Interrupt Break Function" in the MCU tab of the Init dialog box of the emulator debugger.

Thus, normal software breaks are used for the internal RAM and ROM areas of an MCU.

•Do not set a software break at an address where an address-match interrupt occurs. Otherwise, a

user program may be run out of control. Set a software or hardware break in the top address in

address-match interrupt processing.

•When you single step an address where an address-match interrupt occurs, the program stops after

executing the first instruction after returning from address-match interrupt processing.

Notes on Software Breaks:

•Software breaks change the instruction at a specified address to a BRK (00h). Therefore, take note

that when you reference the result of a trace in bus mode, "00h" is displayed.

• The BRK instruction can be used for the emulator only. You cannot use it in a user program.

•You can neither set nor cancel a software breakpoint in the internal ROM area of an MCU during

user program execution, while you can set or cancel it in the internal RAM area of an MCU and

the area (emulation memory) where the map setting is INTERNAL in chip-select CS3* to CS0*.
