Conditions—Natural Convection (Still Air), or EIA/JEDEC Standard JESD51-6, Integrated Circuit Thermal Test Method
Environmental Conditions—Forced Convection (Moving Air).
6 Peripheral operating requirements and behaviors
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)
