No Count
The IN74HC192 can be preset to any state, but
will not count beyond 9. If preset to state 10, 11, 12,
13, 14 or 15, it will follow the sequence 10, 11, 6: 12,
13, 4: 14, 15, 2 if counting Up, and follow the
sequence 15, 14, 13, 12, 11, 10, 9 if counting Down.
Logic equations
For Terminal Count:
TCU = Q0 • Q3 • CPU
TCD = Q0 • Q1 • Q2 • Q3 • CPD
