(3) Changing the Internal Oscillator Circuit of Emulator
A ceramic oscillator circuit for 10 MHz is mounted on this product as a oscillator of a main clock
oscillator circuit when shipped from factory. It is possible to change it to the oscillator circuit board
for 16 MHz (included). How to replace it is shown below. Be sure to read IMPORTANT below before
replacing it.
Figure 3.3 Removing the target connection board (side view)
Apply an equal amount of force to the connectors on each end of the target connection board when pulling the board out.
Note: Do not apply excessive force to the connectors. Excessive force can break the connectors.
Notes on Replacing Internal Oscillator Circuit of Emulator:
(1) Check the operation of the system
(2) Remove the target connection board
Check that the emulator system has no fault by executing the self-check referring "5.3 When
the Operation of the Emulator is Abnormal" (page 44).
Remove the target connection board on the lower board of the emulator as shown in Figure 3.3.
