4-bit binary counter with load/preset value capability

This counter have some unique and interesting features:

  1. It can count up (or count down) in binary
  2. 4 bits means it can count from 0 to F (equivalent of 0 to 15 in decimal)
  3. Can be chained to count over 8, 12, 16, ... bits
  4. Can be preset with arbitrary binary value (loaded via the data bus)
  5. Have "terminal count up" (and "terminal count down") signal to inform when when the count operation did cycle a new sequence.
