نظام المحاضرات الالكترونينظام المحاضرات الالكتروني Addressing Modes 8085 instructions can be classified in following addressing modes Register Addressing mode Instructions which have their operands in registers only e.g. MOV, ADD, SUB, ANA, ORA, XRA etc. Immediate Addressing mode Instructions in which operand immediately follows the op- code e.g. MVI, LXI, ADI, SUI, ANI, ORI etc. Direct Addressing mode Instructions have their operands in memory and the 16- bit memory address is specified in the instruction e.g. LDA, STA, LHLD, SHLD etc.

نظام المحاضرات الالكترونينظام المحاضرات الالكتروني Addressing Modes Contd.. Register Indirect Addressing mode Instructions have their operand in memory and the 16-bit memory address is specified in a register pair e.g. LDAX, STAX, PUSH, POP etc. Implicit Addressing mode These instruction have their operand implied in the op-code itself e.g. CMA, CMC, STC etc.
