-- FUNCTION
-- Movement control multiplexor.
-- Selects either a compressed (A inputs) or decompressed
-- (B inputs) match location and full hit indicator and
-- makes them available on the Y outputs under the control
-- of SELB. If SELB=0 then B inputs are selected.
-- PIN LIST
-- A = match location for compression
-- B = match location for decompression
-- SELB = select
-- ENABLEC = enable compression
-- ENABLED = enable decompression
-- Y = match location output
