a. The leakage current is measured with GND or VDD applied to the corresponding pin(s). The leakage of digital port pins
is measured individually. The port pin is configured as an input and the pullup/pulldown resistor is disabled.
b. Time measured from 20% to 80% of V_DD.
c. Time measured from 80% to 20% of V_DD.
