(3) Using the Internal Oscillator Circuit Bare Board
To use the emulation probe at a frequency you like, build a desired oscillator circuit on the included OSC-2 oscillator
circuit bare board. Figure 3.3 shows an external view of the OSC-2 oscillator circuit bare board and where the connector
pins are located. Figure 3.4 shows the circuitry of the oscillator circuit bare board OSC-2. Use the number of oscillator
circuits recommended by the oscillator manufacturer.
