a. V_DD must be within the range specified in Table 24-2 on page 997.
b. The leakage current is measured with GND or V_DD 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.
c. Time measured from 20% to 80% of V_DD.
d. Time measured from 80% to 20% of V_DD.
