Typical ratings are not guaranteed. The values listed are at room temperature, 5 V.
Ports in quasi-bidirectional mode with weak pull-up (applies to all port pins with pull-ups). Does not apply to open-drain pins.
Ports in PUSH-PULL mode. Does not apply to open drain pins.
In all output modes except high impedance mode.
Port pins source a transition current when used in quasi-bidirectional mode and externally driven from ‘1’ to ‘0’. This current is highest
