     a        :    A3   A2   A1   A0  (16 bits)

-When the partitions are x, the output is:
+Output will always be 48 bits, and the partitions we
+need to confirm but assume will be 4+8=12 bits.
+When the partitions are 1x, the output is:
 
-    partition:          p       p       p           (3 bits)

 By a lucky coincidence the lengths match up.  In the 1x case,
