2. Since the CPU is started by the internal high-speed oscillation clock after a reset release, check
oscillation themselves or apply to the resonator manufacturer for evaluation.
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.

register (OSTC) by the user. Determine the oscillation stabilization time of the OSTC register
and oscillation stabilization time select register (OSTS) after sufficiently evaluating the
oscillation stabilization time with the resonator to be used.
