(2) Using the Internal Oscillator Circuit Board
An oscillator circuit board for 16.0MHz (OSC-3) is mounted on this product. Also the oscillator circuit board (OSC-2) is
attached to change the oscillation frequency. When you use an internal oscillator circuit as a main clock, “Internal” can be set
by the emulator debugger.
