Caution
When using the main system clock and subsystem clock oscillator, wire as follows in the area
enclosed by the broken lines in Figures 7-3 and 7-4 to avoid an adverse effect from wiring
capacitance.
Keep the wiring length as short as possible.
Do not cross the wiring with 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.
Note that the subsystem clock oscillator has a low amplification factor to reduce the current
consumption.
