6. CPU Board Specification

This section describes the specification of the CPU Board.

6.1.1

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. The MCU operation voltage can be selected at either

5 V or 3.3 V for this product. The operation voltage is switched with JP12 as shown in Table 4-6.

6.1.2

This product has the on-board debugger circuit, E2 On-Board (hereinafter called "E2OB"). You can write a

program (firmware) of RX26T with it. When you write a program, open (remove) JP11 and connect the CPU

board to PC with USB cable. E2OB operates as debugger equivalent to E2 emulator Lite. If connecting from

Integrated Development Environment or flash programing tool (e.g. Renesas Flash Programmer), set the type

of debugger (tool) to "E2 emulator Lite".

After writing a program, short JP11 for CPU board operation.
