Cautions 1. When using the X1 oscillator, wire as follows in the area enclosed by the broken lines in the

Resonator
2. Since the CPU is started by the internal high-speed oscillation clock after a reset release,
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.
check the X1 clock oscillation stabilization time using the oscillation stabilization time counter
status 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.
