Nope!  I see more clearly- the HAL input net "Enable" in is FALSE.  That's not 
set inside x200_vfd.comp, but if it ISN'T true, it'll do a write which forces 
the EXT bit which forces the ALARM.

What's up with the ENABLE bit?  I don't have anything connecting that net in 
the HAL file, and it's not getting set to anything.
