Caution The pins mounted depend on the product. Refer to Caution 2 at the beginning of this chapter.
Notes 1. The 78K0R/IB3 doesn’t have the XT1 oscillator.
Cautions 1. When using the XT1 oscillator, wire as follows in the area enclosed by the broken lines in the

above figures to avoid an adverse effect from wiring capacitance.
• Keep the wiring length as short as possible.
• Do not cross the wiring with the other signal lines.
• Do not route the wiring near a signal line through which a high fluctuating current flows.
• Always make the ground point of the oscillator capacitor the same potential as V
• Do not ground the capacitor to a ground pattern through which a high current flows.
• Do not fetch signals from the oscillator.

therefore required with the wiring method when the XT1 clock is used.
