After designing a few quadrature interfaces using a variety of
counters from the usual suspects to the Agilent HCTL line I have yet
to find a chip with a polarity sign bit. One would think that there
are enough machine control applications where direction reversal will
require counting in a negative direction. Granted the index occurs
during zero of both direction's output allowing detection of the first
leading edge to set a flop for polarity but why this isn't a standard
function on the counter chip is beyond me.
