Explanation:
XRL, ORL, and ANL are logical operations in assembly language programming. These commands perform bitwise logical operations on the contents of the accumulator and another register, memory or immediate data.
The correct answer is option 'A', which means that the destination address of these commands is the accumulator, and the source address can be any register, memory, or immediate data. Let's understand each command and its operation in detail.
1. XRL (Exclusive OR Logical)
The XRL command performs a bitwise exclusive OR operation between the accumulator and the specified source operand. The result is stored in the accumulator.
Syntax: XRL A,source
Examples:
- XRL A,R1 ;Exclusive OR contents of R1 with accumulator
- XRL A,#05H ;Exclusive OR immediate data 05H with accumulator
- XRL A,@R0 ;Exclusive OR contents of memory location pointed by R0 with accumulator
2. ORL (OR Logical)
The ORL command performs a bitwise OR operation between the accumulator and the specified source operand. The result is stored in the accumulator.
Syntax: ORL A,source
Examples:
- ORL A,R2 ;OR contents of R2 with accumulator
- ORL A,#0FH ;OR immediate data 0FH with accumulator
- ORL A,@R1 ;OR contents of memory location pointed by R1 with accumulator
3. ANL (AND Logical)
The ANL command performs a bitwise AND operation between the accumulator and the specified source operand. The result is stored in the accumulator.
Syntax: ANL A,source
Examples:
- ANL A,R3 ;AND contents of R3 with accumulator
- ANL A,#08H ;AND immediate data 08H with accumulator
- ANL A,@R2 ;AND contents of memory location pointed by R2 with accumulator
Conclusion:
In summary, XRL, ORL, and ANL commands are logical operations that perform bitwise operations on the accumulator and another register, memory or immediate data. The destination address of these commands is always the accumulator, and the source address can be any register, memory or immediate data.
