@@ -5,6 +5,11 @@ is compared (eq'd), then, depending on the partitions, those partial
 results are ANDed together, on the basis that these chains will tell
 if *all* bits in a particular partition are equal.
 
+Examples:
+
+* p2p1p0 all zeros indicates that the partitions are all closed, turning our 4 input byte-level compares into a 32-bit compare.  by ANDing all 4 byte-levrl compares we get a 32-bit result
+* p2p1p0 equal to 0b010 will split into two 16 bit compares.  therefore, the first two byte-levrl compares are ANDed to give a hi half-word compare and likewise the lower.
