In English, the term 'assert' can have more than one meaning.

Deassert has a specific meaning and is the opposite of assert for only one
of the uses of that word. In formal English there is no such word as
deassert - it is an invented word for technical purposes.

In this case I expect it means to set a logic output high (assert) or low
(deassert). However you have to read it in context.

Looks like this thread has ran its course but I would imagine that it
is a combination of assert = ON and deassert = OFF regardless of a
control pin being active high or active low. In either case you assert
the pin to make it active and it wouldn't matter if it had to be high
or low to do so. Same logic (no pun intended) for deasserting the pin.
Like an output enable for example. That's the way I would look at it.

Definitely so.
