Changing The Internal Oscillator Circuit Of Emulator - Renesas M30800T-CPE User Manual

(3) Changing the Internal Oscillator Circuit of Emulator

An oscillator circuit for 20 MHz is mounted on this product as an oscillator of a main clock (XIN)
oscillator circuit when shipped from factory. When using with the operating frequency other than 20
MHz, it is possible to replace it with a commercially available oscillator circuit board. Figure 3.3
shows the position of the clock and the specifications of the circuit. Table 3.2 lists the recommended
oscillator.

(1) Removing the oscillator
Remove the oscillator mounted on the emulator. The position of the oscillator, see Figure 3.3.
(2) Connecting the oscillator
Mount the oscillator with a desired operating frequency. In this time, care about the direction.

Notes on Replacing Internal Clock of Emulator:
• Take care not to attach the converter board in a wrong direction. It may cause a fatal
damage to the compact emulator.
• Always shut OFF power of the emulator and the target system when connecting and
disconnecting the target system.
