e I/O ramp rate is 10 ns or more. For ramp rates faster than 10 ns, |IIOPIN| = C dv/dt, in which C is the I/O pin capacitance and dv/dt is the slew
rate.

Pin pull-up resistance values may be lower if an external source drives the pin higher than VCCIO
.
Valid with 10% tolerances to cover changes over PVT.
