How do you tell when the a number is entered? The button is a 10-bit
vector that represents the number but how do you tell when it is entered
if entry doesn't happen once per clock cycle. Shouldn't there be a input
signal bit equivalent to the 224H port in the second lab? How do you
tell the difference between entering 2 equal numbers, one after the
other, without this?

Also, the last test case says two buttons are pushed at exactly the same
time. What kind of input will this create. Can you give an example? ie.
input 5 = "0000000101"  and 6 = "0000000110" at the same time gives what
for the 10-bit button?

Why is the button 10-bits when the numbers 0 to 9 only need 4-bits?
