Functions

5.1

Power Supply

The product does not have a dedicated power supply connector. When connected to the INV-BRD, power is supplied
from INV-BRD. When not connected to the INV-BRD, power can be supplied from USB connector. When connected
to INV-BRD, power is supplied from INV-BRD, so power supply from USB connector is not allowed.
5.2

Emulator on Board

The E2 On-Board (E2OB) onboard emulator circuit is equipped in this product, and the RX72M program can be
rewritten using the E2OB. When connecting this product to the PC with USB connectors, the program can be rewritten.
The E2OB functions as an emulator equivalent to E2Lite, so when connecting from the integrated development
environment or Renesas Flash Programmer, set the emulator (tool) type to "E2Lite," the communication interface to
"FINE," and the power supply to "Do not supply.
If you want to use only power supply from USB connector without using E2OB function, remove the short jumper of
JP2 and JP3 and leave them open.
5.3
