AC electrical characteristics
The measurement range of propagation delay is 50% to 50% point and the rise and fall times are measured at 20% and 80% points respectively, as shown in the figure below.
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)
