Pin capacitance is characterized but not tested.
Measured with port in quasi-bidirectional mode.
Measured with port in high-impedance mode.
Ports in quasi-bidirectional mode with weak pull-up (applies to all port pins with pull-ups). Does not apply to open-drain pins.
Port pins source a transition current when used in quasi-bidirectional mode and externally driven from ‘1’ to ‘0’. This current is highest
when V
= 40 C to +85 C for industrial, unless otherwise specified.
