Notes: 1. Indicates only the oscillation circuit characteristics. Refer to “AC Characteristic” for CPU
operation clock.
2. Time, which is required for internal stabilization. The OSTS register has to be set to a time,
which is longer than above defined values, before entering either WATCH or STOP mode.
3. After V_DD5X reaches oscillator voltage range MIN. 4.0 V
4. Start-up time of external crystal or resonator is not included and must be checked with res-
onator supplier.
5. Typical value differs depending on settings of the Oscillation Stabilization Time Selection
register (OSTS)
6. To release watch mode, minimum 10-clock cycles time is required. If sub clock is used to
recover from watch mode, minimum time for watch mode release is determined by this
10-clock cycles.
