In order to let the Dice roll
we need a 3-bit Counter. Whether it should count a sequence like
0,1,2,3,4,5 or 1,2,3,4,5,6 depends on how you designed Driver1.
The best way to implement the
Counter at this point in the course will be Toggle-Flip/flops
The Counter must have one
control input called "Roll" - if Roll=1 must the counter be
active and when Roll=0 must the counter "freeze"
Study how a 4-bit counter
could be implemented with T-F/Fs
