Microprocessor8085. In 8085 Instruction set, INX is a mnemonic that stands for “INcrementeXtended register” and rp stands for register pair. And it can be any one of the following register pairs. rp = BC, DE, or HL. This instruction
will be used to add 1 to the present content of the rp
.
What is difference between INR and INX instruction?
What is the difference between INR and INX instruction?
INR instruction increases the result of a designated register by 1
. IXR instruction increases the result of the whole register pair by 1. For example, in the HL register, INX H will increase the value of the location being pointed by whole HL pair by 1.
What is the function of RAR instruction?
In 8085 Instruction set, RAR stands for “Rotate Accumulator Right involving Cy flag in rotation”. It
rotates the Accumulator contents to the right by 1-bit position.
What operation can be performed by using the instruction XRA A?
XRA A: instruction performs
XOR operation between source operand and destination operand and store the result
in the accumulator. Here, source and destination operand both are same i.e. A. Therefore, the result after performing XOR operation, stored in the accumulator is 00.
What is the function of Ora B instruction?
| Mnemonics, Operand Opcode(in HEX) Bytes | ORA B B0 1 | ORA C B1 1 | ORA D B2 1 | ORA E B3 1 |
|---|
What is full form of RAR file?
Full name. RAR
Archive
File Format Family. Description. RAR, or the Roshal ARchive format thanks to its namesake creator software developer Eugene Roshal, is a proprietary archive file format that supports data compression, error recovery and file spanning.
What type of instruction is pop?
| Mnemonics, Operand Opcode(in HEX) Bytes | POP PSW F1 1 |

What is the function of INX H?
| Mnemonics, Operand Opcode(in HEX) Bytes | INX H 23 1 |

What is the meaning of an instruction INR H?
In 8085 Instruction set, INR is a mnemonic that
stands for ‘INcRement’
and ‘R’ stands for any of the following registers or memory location M pointed by HL pair. R = A, B, C, D, E, H, L, or M. This instruction is used to add 1 with the contents of R. So the previous value in R will get increased by amount 1 only.
What is DCR instruction?
In 8085 Instruction set, DCR is a mnemonic, which stands for ‘
DeCRement
‘ and ‘R’ stands for any of the following registers, or memory location M pointed by HL pair. … Also we can say it will subtract 1 from the register R content. And the decremented value will be stored on to the register R itself.
What is full form of RIM instruction?
In 8085 Instruction set, RIM stands for “
Read Interrupt Mask
”. It is a 1-Byte multi-purpose instruction. It is used for the following purposes –
Is a 3 Byte instruction?
Three-byte instructions –
Three-byte instruction is the
type of instruction in which the first 8 bits indicates the opcode and the next two bytes specify the 16-bit address
. The low-order address is represented in second byte and the high-order address is represented in the third byte.
What is XRA A?
In 8085 Instruction, XRA is a mnemonic that stands for “
eXclusive OR Accumulator
” and “R” stands for any of the following registers, or memory location M pointed by HL pair. R = A, B, C, D, E, H, L, or M. This instruction is used to Ex-OR contents of R with the Accumulator.
How does SBB instruction work?
SBB is a mnemonic that stands for ‘SuBtract with Borrow’ and ‘R’ stands for any of the following 7 registers, and also memory location M as pointed by HL register pair. This instruction is used
to compute subtraction between contents of R register
from the Accumulator’s content, along with the carry (borrow) value.
What the instruction Jnz will do?
The JNZ instruction
transfers control to the specified address if the value in the accumulator is not 0
. If the accumulator has a value of 0, the next instruction is executed. Neither the accumulator nor any flags are modified by this instruction.
Which is the logical instruction?
Logical instructions are the
instructions which perform basic logical operations
such as AND, OR, etc. In 8085 microprocessor, the destination operand is always the accumulator. Here logical operation works on a bitwise level.
