2.1 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.

All digital I/O switching characteristics, unless otherwise specified, assume the output
pins have the following characteristics.
• CL=30 pF loads
• Slew rate disabled
