Prior to having built in latches (16F stuff), I developed a habit of =20
using registers as latches.  Any time I make a change to one of those =20
registers, I update to the port.

RA0,1 are pulled up (to 5Vdd) with 2k resistors.  RA2 is pulled up =20
with a 100k, and has a momentary pushbutton to ground.  Verified RA2 =20
changes between 5V and ground with switch.

Cheers,
-Neil.
