What is the output of LXI H 2050H?
‘) LXI H,2050H L=50H H=20H LXI instruction takes 3 bytes of memory and 10 clock periods.
What is RRC instruction?
The RRC instruction rotates the eight bits in the accumulator and the one bit in the carry flag right one bit position. Bit 0 of the accumulator is rotated into the carry flag while the original value of the carry flag is rotated in to bit 7 of the accumulator.
What is Dad B instruction?
Let us consider DAD B is a sample instruction of this category. As It is 1-Byte instruction so it occupies a single Byte place in the memory. We are considering the initial content of HL and BC register pairs are 4050H and 4060H.
What is the function of Ora B instruction?
This instruction is used to OR contents of R with the Accumulator. The result of OR operation will be stored back in the Accumulator….Instruction type ORA R in 8085 Microprocessor.
| Mnemonics, Operand | Opcode(in HEX) | Bytes |
|---|---|---|
| ORA B | B0 | 1 |
| ORA C | B1 | 1 |
| ORA D | B2 | 1 |
| ORA E | B3 | 1 |
What is LXI H in microprocessor?
We can use this instruction to load data from memory location using the memory address, which is stored in the register pair rp. For an example, if the instruction is LXI H, FE50. It means that the FE50 is loaded into the HL register pair.
What is the 8085 microprocessor?
Definition: 8085 is an 8-bit microprocessor as it operates on 8 bits at a time and is created with N-MOS technology. The size of the data bus of 8085 is 8 bits while that of the address bus is 16. Therefore, can address 64 KB (i.e., 216) memory.
What is the function of RRC in microprocessor?
In 8085 Instruction set, RRC stands for “Rotate Right Accumulator”. With the help of this instruction, we can rotate the Accumulator current content to the right by 1-bit position.
What is Ani microprocessor?
Microprocessor8085. In 8085 Instruction set, ANI is a mnemonic, which stands for “ANd Immediate with Accumulator” and “d8” stands for any 8-bit or 1-Bytedata. This instruction is used to AND 8-bit immediate data with the Accumulator’s content.
What is CMA in microprocessor?
In 8085 Instruction set, logical type there is one complement instruction with the mnemonic CMA. It actually stands for “CoMplement the Accumulator”. Though it is a logicaltype of instruction, Flag bits are not affected by the execution of this instruction. It occupies only 1 Byte in memory.
What is LXI command?
We can use this instruction to load data from memory location using the memory address, which is stored in the register pair rp. …
What is HLT microprocessor?
In the x86 computer architecture, HLT (halt) is an assembly language instruction which halts the central processing unit (CPU) until the next external interrupt is fired. Most operating systems execute a HLT instruction when there is no immediate work to be done, putting the processor into an idle state.
What are the instructions in the 8085 microprocessor?
Instruction Type LXI rp, d16 in 8085 Microprocessor Microprocessor 8085 In the 8085 Instruction set there are four instructions, which belong to the type LXI rp, d16. These instructions are used to load the 16-bit address into the register pair.
What is the RP of the LXI instruction?
The rp can be BC, DE, HL or SP. The LXI instructions and their Hex-codes are as follows. In this example, we can see how the LXI instruction can load 16-bit data into the Register Pairs. Load 56FE into the DE register pair and ABCD into the HL register pair, exchange the content of DE and HL.
Where does the LXI H, fe50 instruction go?
These instructions are used to load the 16-bit address into the register pair. We can use this instruction to load data from memory location using the memory address, which is stored in the register pair rp. For an example, if the instruction is LXI H, FE50. It means that the FE50 is loaded into the HL register pair.
What are the different addressing modes in the 8085?
Types of addressing modes – In 8085 microprocessor there are 5 types of addressing modes: 1 Immediate Addressing Mode –. 2 Register Addressing Mode –. 3 Direct Addressing Mode –. 4 Register Indirect Addressing Mode –. 5 Implied/Implicit Addressing Mode –.
