4.2.2 To use user mounted clock
Either procedure (1) or (2) below must be carried out depending on the clock to be used.
After the screen debugger has been started up, select “USER” on the initial setting screen or the clock configuration
panel (selection of the user clock).
(1) To use a ceramic/crystal oscillator
Prerequisites
• Component block (IE-78000-R accessory)
• Ceramic resonator or crystal resonator
• Resistor Rx
• Capacitor CA
• Capacitor CB
• Soldering tools
Procedure
①
Solder a ceramic resonator or crystal resonator, resistor Rx, capacitor CA, and capacitor CB, all conforming
to the frequency of the oscillator, to the component block.
Remarks
:
The area enclosed by the broken line indicates the portion to be connected to the component block.
