This section describes the specification of the CPU Board.
5.1

Functions

5.1.1

Power supply

When not connected to the inverter board, power should be supplied from the USB connector. When
connecting to the inverter board, power supply from the USB connector or from the inverter board will be
automatically selected. USB power supply has priority.
5.1.2

Onboard debugger

This product has the onboard debugger circuit, J-Link On-Board (hereinafter called "J-Link-OB"). You can
write a program (firmware) of RA6T2 with it. When you write a program, connect the CPU board to PC with
USB cable. J-Link-OB operates as debugger equivalent to J-Link. If connecting from Integrated Development
Environment or flash programming tool (e.g. J-Flash Lite by SEGGER), set the type of debugger (tool) to "J-
Link".
5.1.3
