Fig. 8-3 Examples of Using Oscillator
(1) Crystal/ceramic oscillation
(2) External clock
When EXTC bit of OSTS = 1
When EXTC bit of OSTS = 0
Caution When using the clock generator, to avoid problems caused by influences such as stray
capacitance, run all wiring within the area indicated by the dotted lines according to the following
rules:
Minimize the wiring length.
Wires must never cross other signal lines.
Wires must never run near a line carrying a large varying current.
The grounding point of the capacitor of the oscillator circuit must always be at the same
potential as V
SS
. Never connect the capacitor to a ground pattern carrying a large current.
Never extract a signal from the oscillator circuit.
