If as a result of the AND, the leftmost bit of R+1 is 1, the Negative Flag will
turn ON.
Examples When the execution condition CIO 0.00 is ON, the logical AND will be taken of
corresponding bits in CIO 1001, CIO 1000 and CIO 2001, CIO 2000 and the
results will be output to corresponding bits in D201 and D200.
