4.3 Setting the Subsystem Clock
4.3.1 To use the user mounted clock
36
Procedure (1) or (2) below must be carried out depending upon the type of the clock to be used.
These procedures do not have to be performed on the screen debugger.
(1) To use a ceramic/crystal resonator
Remarks: The area enclosed by the broken line indicates the portion to be attached to the component block.
Prerequisites
• Component block (IE-78000-R accessory)
• Ceramic oscillator or crystal resonator
• Resistor Rx
• Capacitor CA
• Capacitor CB
• Soldering tools
Procedure
Solder a ceramic resonator or crystal resonator, resistor Rx, capacitor CA, and capacitor CB, all conforming to
the frequency of the resonator, to the component block.
