(3) Changing the Internal Oscillator Circuit of the Emulation Pod
An oscillator circuit board for 16.0 MHz (OSC-3) is mounted on this product. 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 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.
