Explanation: In this addressing mode, the value of the register serves as another memory location and hence we use pointers to get the data. 5. In the following indexed addressing mode instruction, MOV 5(R1),LOC the effective address is ______ .
A. EA = 5+R1
B. EA = R1
C. EA = [R1]
D. EA = 5+[R1]
Answer:A

A. EA = 5+R1 B. EA = R1 C. EA = [R1] D. EA = 5+[R1]
Explanation: This instruction is in Base with offset addressing mode. 6. The addressing mode/s, which uses the PC instead of a general purpose register is ______ .
