A counter is designed, the count pulse and the zero signal are input, and the 2 - bit 16 - digit number is output. The counting rule of the counter is as follows: when the cleared signal is effective, the output is 0. When the count pulse rises, the output increases from 0 to FF, then decreases to 1, then increases to Fe, then decreases to 2, and then increases again, counting repeatedly according to this rule.
