1. Typical ratings are not guaranteed. The values listed are at room temperature, 5 V.
2. See other Figures for details. Active mode: I
3. Ports in quasi-bidirectional mode with weak pull-up (applies to all port pins with pull-ups). Does not apply to open drain pins.
4. Ports in PUSH-PULL mode. Does not apply to open drain pins.
5. In all output modes except high impedance mode.
6. Port pins source a transition current when used in quasi-bidirectional mode and externally driven from 1 to 0. This current is highest when
7. Measured with port in high impedance mode.
8. Measured with port in quasi-bidirectional mode.
