Test Conditions
After VDD reaches oscil-
lator voltage range MIN.
Notes 1. Indicates only oscillation circuit characteristics. Refer to AC Characteristics for instruction execution time.
2. Time required to stabilize oscillation after reset or STOP mode release.
Cautions 1. When using the main system clock oscillator, wirinin the area enclosed with the dotted line should
be carried out as follows to avoid an adverse effect from wiring capacitance.
q Wiring should be as short as possible.
q Wiring should not cross other signal lines.
q Wiring should not be placed close to a varying high current.
q The potential of the oscillator capacitor ground should be the same as VSS.
q Do not ground wiring to a ground pattern in which a high current flows.
q Do not fetch a signal from the oscillator.
2. When the main system clock is stopped and the system is operated by the subsystem clock, the
subsystem clock should be switched again to the main system clock after the oscillation stabilization
time is secured by the program.
