Chagrin:
If the pin/input has a name you put a bar over the top of it to indicate that the logic is reversed (that it has an internal pullup). Shouldn't that be sufficient?
I don't see how that is a good idea. It is using a convention to imply a function that is unrelated to that convention.
Who is to say pull up is inveterted? If the pin is high, it is high. If the pin is low, it is low. That's not inverted.
