(2) Changing the Internal Oscillator Circuit of Emulation Pod
An oscillator circuit board for 12MHz is mounted on this product. To use the emulation pod at a
frequency lower than 12MHz, 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 3.5 shows a view of the OSC-2 oscillator circuit board (bare board) and where connector pins
are located. Figure 3.6 shows the circuitry of the OSC-2 oscillator circuit board (bare board). Use the
number of oscillator circuits recommended by the oscillator manufacturer.
