The first byte contains the most insignificant bit of a number of counters, the next byte the next significant bits of the counters. Now you can count all the counters at once using logic operations. It is useful where you only need 2-3 bits for a counter. So, in this application, you can have 8 2-bit counters in two bytes. That help?
