Suppose you wished to add a new instruction to SCOMP, called ANDI, that would
perform a bitwise AND of the Accumulator with the 11-bit operand of the instruction. Assuming
that the implementation of the DECODE state is as follows, what would be the machine
language equivalent of ANDI O? Write a hexadecimal or binary number in the box on the
answer sheet.
