    well you have a reset

    then when reset is at 1 (or 0) you are going to intiialize all your registers.

    when the reset changes you are going to start the counter, if the counter hits your max value you start to decrease it, if it hits 0 it increases again.

    then you are going to do a BCD : http://en.wikipedia.org/wiki/binary-coded_decimal

    to display your values in your 7-seg decoder.. (also see the datasheet to see how your 7-seg decoder works)
