This counter contains four master-slave flip-flops and additional gating to provide a divide-by-two counter and divide-
by-eight counter. This counter has a gated zero reset. To use the maximum count length of this counter, the B input is
connected to the QA output. The input count pulses are applied to input A and the outputs are as described in the
appropriate function table.
