Detailed explanation-1: -Direct Addressing Mode-In this addressing mode, The address field of the instruction contains the effective address of the operand. Only one reference to memory is required to fetch the operand. It is also called as absolute addressing mode.
Detailed explanation-2: -An effective address is the location of an operand which is stored in memory. Here are the addressing modes discussed: Immediate: The operand is included in the instruction. Direct: The effective address of the operand in memory is part of the instruction.
Detailed explanation-3: -In an indirect address mode, the address field of an available instruction gives that address in which the effective address gets stored in memory. The control fetches the instruction available in the memory and then uses its address part in order to (again) access memory to read its effective address.
Detailed explanation-4: -Stack addressing-The effective address is found in a dedicated register implied by the opcode and is auto-adjusted as data is pushed or pulled from stack. Immediate-The effective address is the address of instruction’s operand. More items
