Figure 7-3. Example of Using Oscillation Circuit
(1) Crystal/ceramic oscillation
(2) External clock
EXTC bit of OSTS = 1
EXTC bit of OSTS = 0
Caution
When using the clock oscillation circuit, wire the dotted portion in the above figure as follows to avoid
adverse influences of wiring capacitance.
Keep the wiring length as short as possible.
Do not cross the wiring with other signal lines.
Do not route the wiring in the vicinity of lines through which a high alternating current flows.
Always keep the potential at the ground point of the capacitor in the oscillation circuit the same
as V
SS1
. Do not ground to a ground pattern through which a high current flows.
Do not extract signals from the oscillation circuit.
