IMPORTANT

Notes on Software and Hardware Breaks:

• The software break is a debugging function which breaks a program immediately before the system

executes an instruction at a specified address. The instruction at the preset address will not be

executed.

• The hardware break is a debugging function which breaks a program by setting the detection of an

execution of an instruction at a specified address as a break event. The program will break after the

instruction at the specified address is executed.

• The software break generates BRK interrupts by substituting the proper instruction to the BRK

instruction "00h". 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 disassemble

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.

Note on Stop and Wait Modes:

•Do not perform step execution at addresses in the stop or wait mode. It may cause communication

errors.

Note on Watchdog Function:

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

otherwise, disable the watchdog timer.

Note on DMA Transfer:

•With this product, the program is stopped with a loop program to a specific address. Therefore, if

a DMA request is generated while the program is stopped, a DMA transfer is executed, but it may

not be performed correctly. Also note that the below registers have been changed to generate a

DMA transfer as explained here even when the program is stopped.

DMA0 and DMA1 transfer counter registers TCR0 and TCR1

Note on Pullup Control:

•With this product, ports P0 to P5 are not pulled up by the pullup control register. To pull up the ports

P0 to P5, mount the included network resistor (51 kΩ) to the inside of the emulator as occasion

demands. How to mount it, refer to "3.5 Installing and Removing Network Resistors for Pullup"

(page 38).

Note: Ports P6 to P10 are pulled up by the pullup control registers.

Note: Pullup control registers themselves can be read and written into properly.
