8.2 General
8.2.1 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.
Figure 2. Input signal measurement reference
All digital I/O switching characteristics assume:
• output pins
— have CL=30pF loads,
— are configured for fast slew rate (PORTx_PCRn[SRE]=0), and
— are configured for high drive strength (PORTx_PCRn[DSE]=1)
• input pins
— have their passive filter disabled (PORTx_PCRn[PFE]=0)
