Cautions 1. Subsystem clock oscillator operates on the output voltage of the on-chip regulator.
External clock input is prohibited.
2. When using the subsystem clock oscillator, wire as follows in the area enclosed by the
broken lines in the above figure 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
SS
.
Do not ground the capacitor to a ground pattern through which a high current flows.
Do not fetch signals from the oscillator.
3. Sufficiently evaluate the matching between the

PD703031A, 703031AY, 703033A, 703033AY,
70F3033A, 70F3033AY and the resonator.
