Is the FX2 WAKEUP# pin edge or level triggered? If it is asserted, how long does it need to remain in this state for triggering a wakeup signal.


It is level triggered.

Minimum pulse width can be brief since it just asynchronously resets a flop. We recommend 20 ns (in reality it's actually a lot less, but this is a safe value to choose and still relatively small).
