What is instruction set and list all instruction set of 8085?
Let us take a look at the programming of 8085 Microprocessor. Instruction sets are instruction codes to perform some task. It is classified into five categories….Microprocessor – 8085 Instruction Sets.
| S.No. | Instruction & Description |
|---|---|
| 5 | Data Transfer Instructions Following is the table showing the list of Data-transfer instructions with their meanings. |
How many instructions set are there in 8085?
Number of instructions in 8085 Microprocessor
| Description | No. of opcodes | No. of instruction types |
|---|---|---|
| Arithmetic Instructions | 62 | 14 |
| Logical Instructions | 43 | 15 |
| Stack Instructions | 15 | 9 |
| Branch Instructions | 36 | 8 |
How many types of instructions are there in microprocessor?
1. Data Transfer Instruction set of 8085
| Instruction Set | Meaning | Bytes of Instruction |
|---|---|---|
| MOV r, data [r] ← data | Move immediate data to register | 2-byte |
| LXI rp, 16-bit data [rp] ← 16-bit data; [rh] ← 8 MSBs of data,[rl] ← 8 LSBs of data | Load register pair immediately | 3-byte |
| LDA address [A] ← [[address]] | Load accumulator direct | 3-byte |
Where is the instruction set stored?
memory
Instructions are stored in memory and the contents of the PC register are used as the starting address from where the next to be executed instruction is read. Because the length of an 68k instruction is bytes can vary decoding and reading the instruction from memory (steps 1 and 2) is an iterative process.
What is the instruction set size of 8085 microprocessor?
In 8085, the length is measured in terms of “byte” rather then “word” because 8085 microprocessor has 8-bit data bus. Three types of instruction are: 1-byte instruction, 2-byte instruction, and 3-byte instruction.
What is instruction set and registers in microprocessor?
The instruction set provides commands to the processor, to tell it what it needs to do. The instruction set consists of addressing modes, instructions, native data types, registers, memory architecture, interrupt, and exception handling, and external I/O.

How many flip-flops are there in an 8085 microprocessor?
There is a set of five flip-flops which indicate status (condition) arising after the execution of arithmetic and logic instructions. These are: The symbol and abbreviations which have been used while explaining Intel 8085 instructions are as follows: 16-bit address of the memory location. One of the register pairs.
What is Sim 80 instruction in 8085?
RIM Instruction 80. Control Instructions Opcode Operand Description SIM None Set Interrupt Mask This is a multipurpose instruction and used to implement the 8085 interrupts 7.5, 6.5, 5.5, and serial data output. The instruction interprets the accumulator contents as follows. Example: SIM 81. SIM Instruction
What are the symbol and abbreviations used while explaining Intel 8085 instructions?
The symbol and abbreviations which have been used while explaining Intel 8085 instructions are as follows: 16-bit address of the memory location. One of the register pairs. 16 bit program counter, PCH is high order 8 bits and PCL low order 8 bits of register PC.
