          This part is really ugly.  GSEL (P5.7) must be high to select
          normal voltage, but a lot of applications light to swing it low
          to be a nuissance.  To get around this, we assume that anyone
          with a glitching FET will also have a DAC, then we set that DAC
          to a high voltage.

          At some point, each target must be sanitized to show that it
          doesn't clear P5OUT or P5DIR.
