Implied Mode − In this mode, the operands are specified implicitly in the definition of the instruction. For example, the instruction "complement accumulator" is an implied-mode instruction because the operand in the accumulator …

Addressing Modes of 8085 Microprocessor with Example
WebJul 4, 2024 · The relative mode has three types: PC Relative, Index Register Relative, and Base Register Relative Addressing modes. Direct addressing mode has no types. It results in a shorter address field in the instruction format as the relative address can be specified with a small number of bits. It results in a longer address field in the instruction ... WebJul 5, 2024 · Direct addressing mode. In direct addressing mode, the address of the operand is directly specified in the instruction. In this addressing mode, the instruction is two or three bytes long. The first byte is the Opcode. The operand may be a 16-bit (2 bytes) memory address or an 8-bit (1 byte) port address. Web3) The instructions using direct addressing mode are three-byte instructions. Byte 1 is opcode of the instruction, Byte 2 is lower order address and Byte 3 is high order address. 4) For e.g. LDA 9FFFH. i.e. This instruction loads accumulator with the content of memory location 9FFF H.
