Main System Clock Oscillator Characteristics

= 2.7 to 5.5 V)
Notes 1.
Only the oscillator characteristics are shown. For the instruction execution time, refer to
AC Characteristics
.
2.
Time required for oscillation to stabilize after a reset or the STOP mode has been released.
Cautions 1.
When using the oscillation circuit of the main system clock, wire the portion enclosed in dotted lines
in the figures as follows to avoid adverse influences on the wiring capacitance:
Keep the wiring length as short as possible.
Do not cross the wiring over other signal lines.
Do not route the wiring in the vicinity of lines through which a high fluctuating current flows.
Always keep the ground point of the capacitor of the oscillation circuit at the same potential as
V
SS
.
Do not connect the power source to a ground pattern through which a high current flows.
Do not extract signals from the oscillation circuit.
2.
When the main system clock is stopped and the device is operating on the subsystem clock, wait
until the oscillation stabilization time has been secured by the program before switching back to
the main system clock.
