Note2-1: VDD must be held greater than or equal to 3.0V when onboard writing to flash ROM.
Note2-2: Relationship between tCYC and oscillation frequency is 1/FmCF at a frequency division ratio of 1/1 and
2/FmCF at a division ratio of 1/2.
Note2-3: See Tables 1 and 2 for the oscillation constants.
Note2-4: Ta=0°C to 60°C
