Notes 1.
Only the characteristics of the oscillation circuit are indicated. See the description of the AC
characteristics for the instruction execution time.
2.
Time required for oscillation to settle once a reset sequence ends or STOP mode is deselected.
Caution
When using the system clock oscillation circuit, observe the following conditions for the wiring
of that section enclosed in dotted lines in the above diagrams, so as to avoid the influence of
the wiring capacitance.
Keep the wiring as short as possible.
Do not allow signal wires to cross one another.
Keep the wiring away from wires that carry a high, non-stable current.
Keep the grounding point of the capacitors at the same level as V
SS
.
Do not connect the grounding point to a grounding wire that carries a high current.
Do not extract a signal from the oscillation circuit.
