3. Assume that the machine described in Appendix C uses memory-mapped I/O and that the address A0 is the location within the printer port to which data to be printed should be sent. If register 5 contains the ASCII code for the letter A, what machine language instruction should be used to cause that letter to be printed at the printer? (5 points )The Machine Language in Appendix C IRXY LOAD the register R with the bit pattern found in the memory cell whose address is XY. 2RXY LOAD the register R with the bit pattern XY. 3RXY STORE the bit pattern found in register R in the memory cell whose address is XY 40RS MOVE the bit pattern found in register R to register S. 5RST ADD the bit patterns in register S and T and as though they were two's complement representations and leave the result in register R. 6RST ADD the bit patterns in register S and T and as though they represent values in floating-point notation and leave the result in register R. 7RST OR the bit patterns in registers S and T and place result in register R. 8RST AND the bit patterns in registers S and T and place result in register R. 9RST XOR the bit patterns in registers S and T and place result in register R. AROX ROTATE the bit pattern in register R one bit to the right X times. Each time place the bit that started at the low order end at the high order end. BRXY JUMP to the instruction located in the memory cell at address XY if the bit pattern in register R is equal to the bit pattern in the register number 0. Otherwise, continue with normal sequence of execution.
