In the example above, we can see the effects of the mc/mcr on an outb(outbar) instruction. Remember that if the mc/mcr block were not there 0500 would be physically on only when input 0001 was false(physically off). But since the mc/mcr block is there, this happens only when input 0000 is true. When input 0000 is false it is impossible for 0500 above to be on.
