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 CL=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)
