I would have thought you'd want to *enable* termination power if you
were going to use an external active terminator. Where else is it going
to get power from?
Normally from the controller, surely? You would only enable term. power if the
controller doesn't supply it, and then only on one device, at the end of the chain.
Unless, you mean to ensure that you don't have several devices on the
bus trying to supply termination power.
That's the principle reason. IIRC, on some old devices turning on internal term.
power also enabled internal termination, so you wouldn't want an external
terminator in that case.
