EXPLAIN ALL STEPS: Convert the following machine language instructions into assembly language, assuming that they were not generated by pseudo-ops: a) 82B7DE b) 04 c) DF63DF
EXPLAIN ALL STEPS: Convert the following machine language instructions into assembly language, assuming that they were not generated by pseudo-ops:
a) 82B7DE
b) 04
c) DF63DF
a.
82B7DE
Convert the above machine language into binary format
1000 0010 1011 0111 1101 1110
1000 raaa
The equivalent Mnemonic for 1000 raaa is AND r (Bitwise AND to r instruction)
Here, r = 0 so the “r” value is A
aaa = 010
The addressing mode for 010 is “Indirect” and letter for “010” is “n”
Operand specifier = B7DE
Therefore, the answer is ANDA 0xB7DE, n
b.
04
