Hello.
I have a question.
Could you tell me detail condition when VOL = 0.6V?
I think VOL max is too high.

Hi Keirs,
Below is the table from the MSP430FR2310 datasheet for reference.
Typically, when a GPIO is configured as an output and driven low ( = 0), the voltage on the pin is expected to be 0v.
However, this is not always the case, depending on the voltage,temperature and the current flowing through a pin.
It can also vary from device to device, so when you consider that TI manufactures billions of devices, there will be some expected variability.
What this specification really describes is the maximum (or worst case) low voltage that may appear on any GPIO. This means if you sample 1000 devices, you will find output voltages on any of the GPIO pins to be somewhere between 0v and 0.6v. This also is tested and screened in the factory.
Normally this shouldn't be a problem when interfacing to other logic devices, CMOS, TTL, as their VIL (input low voltage threshold) will be higher than this and be detected as a "low" input.
Does this help answer this question? If not, tell me a little more about your application and maybe I can help remove any concerns.
