Convert the 48 machine language instructions into assembly language, assuming that they were not generated by pseudo-ops_______________?

Correct answer: A. ASRA

  • A. ASRA
  • B. ADDA h#01FE, i
  • C. LOADA h#OD4E, i
  • D. STOREA h#014B, d

Explanation

In the referenced instruction format, hexadecimal machine code 48 decodes to ASRA, an accumulator arithmetic-shift-right instruction. The other choices include operand-bearing instructions and therefore do not match this unary opcode.
