IMPORTANT

Note on Instructions that Access the Single-step Interrupt Vector Area:

• Do not perform the below debugging operations with the single step interrupt vector area (addresses

FFFECh--FFFEFh).

(1) Step execution of instructions that access the single step interrupt vector area

(2) Program execution from the instruction accessing the single step interrupt vector area when

a software breakpoint is set at the instruction

Notes on Software Breaks and Hardware Breaks:

• Software breaks generate BRK interrupts by substituting the proper instruction to the BRK

instruction. Therefore, when referencing the result of a trace in bus mode, "00h" is displayed for

the instruction fetch address where a software break is set, and when referencing in reverse

assemble mode, "BRK" instruction is displayed.

• It is not possible to use a software break and a hardware break at the same time. If doing so, it may

not operate normally.

• In the area where the MAP setting is EXTERNAL, software breaks cannot be used.

Notes on Watchdog Function:

• The MCU's watchdog timer can be used only while programs are being executed. To use it

otherwise, disable the timer.

• If the reset circuit of the target system has a watchdog timer, disable it when using the emulator.

Note on Self-checks:

•With this product, the self-checks of the emulator main unit PC4701 does not work properly.

Note on Changing the Setting of Memory Area:

• To debug an MCU whose memory size is different, be sure to change the setting of the memory area

(see 3.5 Procedure for Making an MCU File for the M3T-PD30 on page 30). For details on memory

maps of each MCU, refer to the user's manual of each MCU.
