예를 든다면 어떤 칩이 high일때 동작하고 low일때 sleep 모드로 진입한다면 이건 active high이다.



# assert, deassert

Given the copious context you've provided, this is just a guess:

assert: set a signal to its "active" state.

deassert: set a signal to its "inactive state.

If a signal is active-low, "asserting" that signal means setting it low and deasserting it means setting it high.
