Note 2-3: See Tables 1 and 2 for the oscillation constants.
Note 2-4: When switching the system clock, allow an oscillation stabilization time of 100s or longer after the
frequency variable RC oscillator circuit transmits from the "oscillation stopped" to "oscillation enabled" state.
Functional operation above the stresses listed in the Recommended Operating Ranges is not implied. Extended exposure to stresses beyond the Recommended
Operating Ranges limits may affect device reliability.
