 	  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.
