Caution The pins mounted depend on the product. Refer to Caution 2 at the beginning of this chapter.
Note Indicates only oscillator characteristics. Refer to AC Characteristics for instruction execution time.
Cautions 1. When using the X1 oscillator, wire as follows in the area enclosed by the broken lines in the above
= −40 to +85°C, 1.8 V ≤ V
Resonator
2. Since the CPU is started by the internal high-speed oscillation clock after a reset release, check
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.
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
the oscillation stabilization time select register (OSTS) after sufficiently evaluating the oscillation
stabilization time with the resonator to be used.
