    Yes, you could run a clock into the RC oscillator and it would allow
    you to wake up without the 1024 Tosc.  However, we don't recommend it
    because there is an internal pulldown transistor that you will have to
    override which will burn a lot of unnecessary current and my affect
    the long term reliability of the device.

    Rgds, Brian.

Right, for powerup those timings apply.  For a reset from sleep, however,
only the 1024tosc [if XT, HS, or LP] is applied [nothing at all if RC].  My
question is whether it's possible to use the RC mode with an external osc-
illator so as to dispense with the extra 1024tosc.
