2.3.2 Using the Internal Oscillator Circuit Board
An oscillator circuit board for 16.0 MHz (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.
2.3.3 Changing the Internal Oscillator Circuit of the Emulation Pod
To use the emulation pod at a frequency other than 16.0 MHz, build the desired oscillator circuit on the included OSC-2
oscillator circuit board (bare board) and replace the board installed in the emulation pod when shipped from the factory.
Figure 2.3 shows an external view of the OSC-2 oscillator circuit board (bare board) and where connector pins are located.
Figure 2.4 shows the circuitry of the OSC-2 oscillator circuit board (bare board). Use the number of oscillator circuits
recommended by the oscillator manufacturer.
