1. Kinds of Oscillator Boards
The R0E521000CPE00 comes with an oscillator circuit board OSC-3 (20 MHz). And an oscillator circuit bare board OSC-2 is
included with this product. If you use an internal oscillator circuit board of the emulator as a main clock, choose "Internal" in
the emulator debugger after replacing oscillator circuit boards to change a clock supplied to an MCU.
