(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.
IMPORTANT
Notes on Replacing Internal Oscillator Circuit of Emulator:
• Soldering is required to replace the emulator's internal oscillation circuit. If you are
inexperienced at soldering, it is recommended to supply a clock of arbitrary
frequency from an external source.
• The included 16MHz oscillator is the only oscillator that can be used as a
replacement. Other oscillators may not oscillate properly, therefore supply a clock
of arbitrary frequency from an external source.
• Emulator standalone operation is not guaranteed when a 16MHz oscillator is
installed. During standalone operation, the emulator operates at 3.3 V, which
exceeds the guaranteed operating frequency of the MCU.
• Generally, the oscillator can be replaced only twice (removal and installation count
as one time). Any more than this will effect board pattern durability, it is not
recommended.
• Be careful not to damage other devices when replacing the oscillator. Servicing for
damage incurred during oscillator replacement can be subject to billing even in the
warranty period.
(1) Check the operation of the system
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).
(2) Remove the target connection board
Remove the target connection board on the lower board of the emulator as shown in Figure 3.3.
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.
