What is an addressing mode Identify the addressing mode for

What is an addressing mode? Identify the addressing mode for each of the following instructions (both for the source and destination operands where it applies). MOV P1. #30H ADD A, #20 MOVR7.A MOV @R0, A INC DPTR ORL 20H, #30H CJNE A, 3011. NEXT DJNZ R4, BACK JMP @A+DPTR ACALL DELAY MOV 20H,00H MOV 00H, @R0 MOVC A, @ A+DPTR MOVX A, @DPTR PUSH 20H SJMP FORWARD

Solution

2) Addressing modes are an aspect of the instruction set architecture in most central processing unit (CPU) designs. The various addressing modes that are defined in a given instruction set architecture define how machine language instructions in that architecture identify the operands of each instruction.

B) Immediate Addressing Mode.

C) Immediate Addressing Mode.

D) Register Addressing Mode.

E) Direct Addressing

F) Register Addressing

G) Immediate Addressing

H)Direct Addressing.

I) Register Indirect Addressing.

J) Indirect Addressing.

K) Absolute Addressing.

L)Direct Addressing.

M) Register Indirect.

N) Index Addressing.

O) External Direct Addressing.

P) Direct Addressing.

Q) Relative Addressing.
