The output flags are set depending upon the output of the out[16]

Say you had a 2 bit number 00. Can you think of a way of using chip(s) to return a 0 only if both
bits were 0? If you can then you're almost there

For ng, do you know how to output only a selected one bit-wide number from a 16 bit number?
If you don't the appendix on hdl will tell you.
