Kinds of Oscillator Circuit Boards
An oscillator module (20MHz) is mounted on the IC17 at factory setting. If you 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 of the IC17 (see Figure 2.7).
