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.
IMPORTANT
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 26). 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 38).
If using this product when the voltage of VCC1 is higher than that of VCC2, the CPU clock must be 24 MHz or
less.
