Note:

1. Under steady state (non-transient) conditions, IOL must be externally limited as follows:

Maximum IOL per port pin: 10 mA

Maximum IOL per 8-bit port

Port 0: 26 mA

Ports 1, 2, 3: 15 mA

Maximum total IOL for all output pins: 71 mA

If IOL exceeds the test condition, VOL may exceed the related specification.
