Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Which one of the following addressing technique is not used in 8085 microprocessor?

A	Register
B	Immediate
C	Register Indirect
D	Relative

Explanation:

Detailed explanation-1: -Thus, the correct option is (D) Relative addressing mode is not used in the 8085 microprocessor. The 8085 microprocessor uses other addressing modes like register, immediate, direct, and indirect addressing modes to access the memory and input/output devices.

Detailed explanation-2: -An 8085 microprocessor uses five addressing modes: Immediate addressing mode, Register addressing mode, Register indirect addressing mode, Direct addressing mode, and Implicit addressing mode.

Detailed explanation-3: -Therefore, the correct answer is option ‘C’ i.e. Status register.

Detailed explanation-4: -In the 8085 Instruction set, there are four instructions, which belong to the type LXI rp, d16. These instructions are used to load the 16-bit address into the register pair. We can use this instruction to load data from the memory location using the memory address, which is stored in the register pair rp.

Detailed explanation-5: -Expert-Verified Answer. Explanation: In Memory Direct Addressing Mode the data transfer between memory-to-memory is not possible.
