4.5 Notes on Using This Product

Notes on using this product are listed below. When debugging the MCU using this product, be careful about the following

precautions.

Notes on Downloading Firmware:

Before using this product for the first time, it is necessary to download the dedicated firmware (control

software built into the PC7501). Please note that, to do this, it is necessary to start up the PC7501 in

maintenance mode. For firmware download procedures, see "2.7 Downloading Firmware" (page 28).

Once the firmware has been downloaded, the product can be used by simply turning on the power.

Do not shut off the power while downloading the firmware. If this happens, the product will not start up

properly. If power is shut off unexpectedly, redownload the firmware.

Except when a target status error occurs, if the self-check is not completed successfully, there may be

trouble with the product. In such case, contact your sales representative.

Perform the self-check while not connecting the user system.

Note on Quitting the Emulator Debugger:

To restart the emulator debugger after it ends, always shut power to the emulator module off once and

then on again.

Notes on Power Supply to the User System:

Pin Vcc of the emulator is connected to the user system to observe the voltage of the user system.

Therefore design your system so that the user system is powered separately.

The voltage of the user system should be within the following.

(1) When JP1 is set as VCC1 = 2:

3.0 V ≤ VCC1 = VCC2 ≤ 5.5 V

(2) When JP1 is set as VCC1 > 2:

4.8 V ≤ VCC1 ≤ 5.2 V

3.0 V ≤ VCC2 < VCC1

Do not change the voltage of the user system after turning on the power.

Notes on Using This Product When the Voltage of VCC1 is Higher than That of VCC2:

If using this product when the voltage of VCC1 is higher than that of VCC2, set the JP1 to VCC1>2. For

the switch JP1, refer to "2.10 Setting Switches" (page 40).

If using this product when the voltage of VCC1 is higher than that of VCC2, the CPU clock must be 24

MHz or less.
