Consider the sequence of 8085 instructions given below—
LXI H, 9258
MOV A, M
CMA
MOV M, A
Which one of the following program is performed by this sequence?
-
- Contents of location 9258 are moved to the accumulator
- Contents of location 9258 are compared with the contents of the accumulator
- Contents of location 8259 are complemented and stored in location 8529
- Contents of location 5892 are complemented and stored in location 5982
Correct Option: A
LXI H, 9258 H ← Store the location in HL register pair 
MOV A, M ← Store data on address 9258 H moved to accumulator
CMA ← Complement the content of A.
MOV M, A ← Complement data move to 9258 memory location.
So, the best option is (A) as data is moved from memory location 9258 H to the accumulator.
