(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 2.20 shows an external view of the OSC-2 oscillator circuit bare board and where the connector pins are
located. Figure 2.21 shows the circuitry of the oscillator circuit bare board OSC-2. Use the number of oscillator circuits
recommended by the oscillator manufacturer.
