Changing The Internal Oscillator Circuit Of The Emulation Pod - Renesas Emulation Pod M306H2T-RPD-E User Manual

(2) Changing the Internal Oscillator Circuit of the Emulation Pod

An oscillator circuit board (OSC-3) for 10 MHz is mounted on this product. To use the emulation pod
at a frequency other than 10 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 3.6 shows a view of the OSC-2 oscillator circuit board (bare board) and where connector pins
are located. Figure 3.7 shows the circuitry of the OSC-2 oscillator circuit board (bare board). Use the
number of oscillator circuits recommended by the oscillator manufacturer.
