2. Indicates only oscillator characteristics. Refer to AC Characteristics for instruction execution time.
3. Time required to stabilize oscillation after reset or STOP mode release.
When using the system clock 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.
