Note 2-1: VDD must be held greater than or equal to 3.0V in the flash ROM onboard programming mode.
Note 2-2: Relationship between tCYC and oscillation frequency is 3/FmCF at a division ratio of 1/1 and 6/FmCF at
a division ratio of 1/2.
Note 2-3: See Tables 1 and 2 for the oscillation constants.
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.
