Using The Oscillator Circuit Bare Board - Renesas Emulation Probe M30850T-EPB User Manual

(3) Using the Oscillator Circuit Bare Board

The oscillator circuit board OSC-3 (for 30 MHz) is preinstalled to the emulator main unit. To use it
at 32 MHz, replace the board with the included OSC-3 (for 32 MHz). To use it at a frequency other
than 30 or 32 MHz, 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 oscillator circuit bare board OSC-2. Use the number of oscillator
circuits recommended by the oscillator manufacturer.
