Various formats of specifying the operands are called
addressing modes.
1) Direct, (ex: IN/OUT Port#) (# - port number)
2) Immediate, (ex: MVI R,Data) (R-register)
3) Register, (ex: MOV Rd,Rs) (Rd- destination Register, Rs-
source Register)
4) Register indirect
Is This Answer Correct ?    142 Yes 59 No

1.Direct Addressing mode (eg:IN 00H,OUT 05H).

2.Immediate Addressing mode (eg:MVI 56H).

3.Register Addressing mode (eg:MOV Rd Rs)-Rd=Destination
register and Rs=Source register.

4.Indirect Addressing mode (eg:LDA M)-M=Memory content
address(R/RW memory) stored in one of the register pair(16-

5.Implicit Addressing mode (eg:CMA)-Complements accumulator.
Is This Answer Correct ?    6 Yes 0 No
