2019年7月30日 · STAX B is an example instruction of this type. It is a 1-Byte instruction. Let us suppose that the initial content of BC register pair is 4050H and Accumulators initial content is ABH. At memory location 4050H, it is having initial content of CDH.

2017年9月5日 · Eg: - STAX B (the content of accumulator is stored into the memory location specified by the BC register pair.) 9.SHLD(store H and L register direct): - The contents of register L are stored into the memory location specified by the 16-bit address in the operand and the contents of H register are stored into the next memory location by ...

MOV A, B: Move the content of B register to register A. 78: The instruction in the code form. In the above example, MOV A, B is 78H. Besides the operation to be performed the opcode also specifies source and destination registers. The opcode 78H can be written in …

2024年10月19日 · In 8085 Microprocessor there are 5 Types of Addressing Modes. In immediate addressing mode the source operand is always data. If the data is 8-bit, then the instruction will be of 2 bytes, if the data is of 16-bit then the instruction will be of 3 bytes.

This instruction copies the contents of C register in B register 2. Two byte instruction: FORMAT For example: MVI B, 08H. The opcode for this instruction is 06H and is always followed by a byte data (08H in this case). This instruction is a two byte instruction which copies immediate data into B register MP & MC APPLICATIONS

This page covers 8085 instruction set.The 8085 instructions are specified with opcode,operand,size,M-cycle,T-cycle etc.

STAX Register (Store Accumulator by Extended Register) It is a stored accumulator indirect instruction. In this instruction, the register is available as the operand that holds a memory address. Thus, the accumulator data can be copied to …

2020年4月2日 · In this post, we’ll start with the data transfer instructions. There are varying sizes of an instruction depending on the size of the opcode and the operand. The 8085 is an 8-bit processor, and the smallest size of the machine code of its instruction is 8-bit or 1 byte.

2024年11月18日 · What is STAX Instruction in 8085 Microprocessor? STAX rp. Store content or data of accumulator into the memory address which is held by register pair. For example, STAX B. Suppose, register pair B and C holds memory address 2050H and …

2021年11月12日 · Data transfer instructions copies data from a source to a destination without modifying the contents of the source. They perform the following six operations: Load an 8 bit number in a register. Copy from register to register. Copy between I/O and accumulator. Load 16-bit number in a register pair. Copy betwwen register and memory.
