1. It applies for all port pins except Tamper pins.
2. It covers digital pins except Tamper pins.
3. Analog pins are defined as pins that do not have an associated general purpose I/O port function.

5.1 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.
Figure 1. Input signal measurement reference
All digital I/O switching characteristics assume:
1. output pins
• have C_L=30pF loads,
• are configured for fast slew rate (PORTx_PCRn[SRE]=0), and
• are configured for high drive strength (PORTx_PCRn[DSE]=1)
2. input pins
• have their passive filter disabled (PORTx_PCRn[PFE]=0)
