Question:
For the given 8086 microprocessor instructions below, which of the following is an invalid instruction?
For the given 8086 microprocessor instructions below, which of the following is an invalid instruction?
Show Hint
Always move segment values through general-purpose registers in 8086 microprocessors.
Updated On: Feb 7, 2025
- MOV BX, [0301 H]
- MOV CX, 037AH
- MOV AL, BL
- MOV DS, 4100H
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
- Directly loading an immediate value into the segment register (like DS) is invalid.
- Instead, the value must first be loaded into a general-purpose register and then moved to the segment register.
Conclusion: The invalid instruction is given by option (d).
