Instruction & Data Formats. 1-byte Instructions. Eg. MOV A, M, CMA, DAA etc. 2-byte Instructions. Eg. MVI A, 08, IN 02, CPI 03 etc. 3-byte Instructions. Eg. LXI H, 4500, STA 4600, LDA 4200. ADDRESSING MODES. DEEPAK.P. 10. 1/8/14. Addressing Modes of 8085. The microprocessor has different ways of specifying the
source of data or the address of destination of result is given in the instruction is called Addressing. Modes. The term addressing mode refers to the way in which the operand of the instruction is specified. 3. Gursharan Singh Tatla. Page 4. Types of Addressing Modes. Intel 8085 uses the following addressing modes: 1.
3 Jul 2014 In these instructions the source can be a register, an input port, or an 8-bit number (00H to FFH). Similarly, a destination can be a register or an output port. The sources and destination are operands. The various formats for specifying operands are called the ADDRESSING MODES. For 8085, they are: • 1.
The 68HC11 architecture support addressing modes that allow the basis to understand the addressing modes on any architecture. 5. ECE265. Immediate Addressing (IMM). In immediate addressing the instruction itself contains the data to be loaded into the destination. Consider the instruction. LDAA #15 This instruction
Computer Architecture and Organization. Instruction Sets: Addressing Modes and Formats. Addressing Modes. Immediate; Direct; Indirect; Register; Register Indirect; Displacement (Indexed); Stack. Immediate Addressing. Operand is part of instruction; Operand = address field; e.g. ADD 5. Add 5 to contents of accumulator
and Architecture 8th Edition. Chapter 11. Instruction Sets: Addressing Modes and Formats. Addressing Modes. Immediate; Direct; Indirect; Register; Register Indirect; Displacement (Indexed); Stack. Immediate Addressing. Operand is part of instruction; Operand = address field; e.g. ADD 5. Add 5 to contents of accumulator
The most common fields found in instruction formats are: • An operation code field that specifies the operation to be performed. • An address field that designates a memory address or a processor register. • A mode field that specifies the way the operand or the effective address is determined. Opcode. Mode Instruction fields.
18 Nov 2016 A short ppt on addressing modes in 8085. 8085 ADDRESSING MODES • The ways by which operands are specified in an instruction are called addressing modes. • Different Direct Addressing Mode • If the address of the data is specified in the instruction itself, then it is called direct addressing mode.

- ? MODE FIELD:
- An example of an instruction format with a distinct addressing mode field is shown below:
- Opcode Mode Address
- The mode field is used to locate the Operands needed for the operation. There may or may not be the address field
