Solved! Go to Solution.
The table says that an output voltage higher than the 0.5V is not consider output low voltage. 0.4V is considered as Vol, so when the Vdd is between 1.71V and 2.7V and it is configured as high drive strength the Iol is 3mA.
The I2C module supports System Management Bus so the device can behave as the SMBus requires.
If you have more questions do not hesitate to ask me.

Hello
The I2C module complies with the System Management Bus (SMBus) Specification, version 2. In the datasheet, table 4. The value of 0.4V in symbol VOL is included since the maximum range for VOL is 0.5V.
Let me know if this is helpful, if you have more questions do not hesitate to ask me.

Omar, can you "Please" Verify that when the I/O Pins are Configured as Open-Drain and used for a System Management Application, that Vol will be 0.4V "Maximum" as long as Sink Current is "Less Than" or Equal to 3mA Sink?
In other words, I will "NEVER" see Vol = 0.5V in System Management Applications.......Correct?
