MAIN SYSTEM CLOCK OSCILLATOR CHARACTERISTICS

DD
= 2.7 to 5.5 V)
Notes 1.
It indicates only the oscillator characteristics. For the instruction execution time, see the AC Charac-
teristics.
2.
Time required until oscillation becomes stable after V
DD
is applied or the STOP mode is disabled.
Cautions 1. If the main system clock oscillator is to be used, wire the area inside the broken line square
as follows to avoid influence of wiring capacitance:
Make wiring as short as possible.
Do not cross other signal lines.
Do not get close to lines with fluctuating large current.
Make sure that the connecting points of the capacitor of the oscillator always have the same
electric potential as V
SS
.
Do not connect the oscillator to a ground pattern that conducts a large current.
Do not take out signal from the oscillator.
2. When switching to the main system clock again after the subsystem clock has been used with
the main system clock stopped, be sure to set the program to provide enough time for the
oscillation to stabilize.
