4.5 Notes on Using This Product
Notes on using this product are listed below. Be sure to read these notes before using this product.
IMPORTANT
Notes on Downloading Firmware:
z 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.
z 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.
z 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.
z Perform the self-check while not connecting the user system.
Note on Quitting the Emulator Debugger:
z To restart the emulator debugger after it ends, always shut power to the emulator module off once and then on
again.
Notes on Clock Supply to an MCU:
z Clock can be supplied to the evaluation MCU in one of the following three ways. This is determined by
emulator debugger clock selection.
(1) When Internal is selected:
The clock generated by the oscillation circuit in the PC7501 is supplied to the evaluation MCU. The clock
is continually supplied to the evaluation MCU regardless of "user system clock status" and "user program
execution status".
(2) When External is selected:
The clock oscillating on the user system is supplied to the evaluation MCU. Clock supply to the evaluation
MCU depends on oscillation status (oscillate/off) of the user system.
(3) When Generate is selected:
A clock generated by the dedicated circuit in the PC7501 is supplied to the evaluation MCU. The clock is
continually supplied to the evaluation MCU regardless of "user system clock status" and "user program
execution status".
z When operating this product with a sub clock, be sure to set the SW2 and SW3 to XCIN and NC, respectively.
