3. Analog pins are defined as pins that do not have an associated general purpose I/O port function.
5.3 General
5.3.1 AC electrical characteristics
Unless otherwise specified, propagation delays are measured from the 50% to the 50%
point, and rise and fall times are measured at the 20% and 80% points, as shown in the
following figure.
