Criteria used to define the maximum frequency of the I/Os:
• output duty cycle (40%-60%)
• minimum output swing: 100 mV to VDDIO - 100 mV
• Addition of rising and falling time inferior to 75% of the period
from 3.0V to 3.6V, maximum external capacitor = 40 pF
from 2.3V to 2.7V, maximum external capacitor = 30 pF
from 1.65V to 1.95V, maximum external capacitor = 20 pF
