Program Write
The Evaluation Board is equipped with an on-board emulator for flash write. Connect your PC to the USB501
connector on the Evaluation Board with a USB micro-B cable for the firmware write. Use applications such as
e
studio, CS+, or Renesas Flash Programmer to write firmware. The on-board emulator circuit connected to
2
the PC is recognized as E2 Lite, please set the connection accordingly. Refer to the document of e
CS+, Renesas Flash Programmer in detail.

By using the on-board emulator function, it is possible to debug while executing the firmware. However, when
driving a motor, debugging using this function is not recommended for the following reasons.
When driving a motor, it is recommended to use the RMWB function. For details about RMWB, refer to
Chapter 6.
•
If the MCU is STOPPED from the emulator while the motor is driving, the output of the timer stops at a fixed output, and the current
continues to flow to a fixed phase, possibly causing burnout.
•
When using the on-board emulator function, the PC and the Evaluation Board share the same GND. If the GND is shaken by motor
drive, the PC may be damaged. (The circuit (ICS) used in the RMWB contains an isolator, so the GND of the PC and the Evaluation
Board is not shared, allowing safe evaluation.)
