2.8.2 Using an Internal Oscillator Circuit Board
Kinds of Oscillator Circuit Boards
An oscillator module (8 MHz) is mounted on IC21 at shipment of the R0E417250MCU00. If you wish to change the
frequency, replace the oscillator module.
(1) Replacing the Oscillator Module
Remove the MCU unit from the E100 emulator main unit, and replace the oscillator module on IC21 (see Figure 2.7).

Figure 2.7 Replacing the oscillator module
CAUTION
Note on Replacing the Oscillator Module and Oscillator Circuit Board:
z Always shut OFF power when replacing the oscillator module. Otherwise, internal circuits may be damaged.
z When replacing the oscillator module, remove it with a tool such as an IC extractor so as not to damage the
board. If the board is damaged, the pattern on the board may be cut and the emulator may not be able to operate.
