In 8085 Instruction set, SIM stands for “Set Interrupt Mask”. It is
1-Byte instruction
and. it is a multi-purpose instruction.
What is Sim in contest of microprocessor?
SIM stands for
set interrupt mask
which is handling the interrupts in 8085 microprocessor.
What is the use of SIM instruction?
| Sr. No. Sim Instruction Rim Instruction | 5 SIM instruction can be used for serial output of data. RIM instruction can be used for serial input of data. |

What is the function performed by SIM and RIM instruction?
In 8085 Instruction set, SIM (Set Interrupt Mask) and RIM (Read Interrupt Mask) instructions can
perform mask and unmask RST7
.
What is an instruction in microprocessor?
An instruction of a computer is a command given to the computer to perform a specified operation on given data. In microprocessor, the instruction set is
the collection of the instructions that the microprocessor is designed to execute
. The programmer writes a program in assembly language using these instructions.
What is true about Sim instruction?
This bit can have two values: 0or 1. If MSE bit = 0, SIM instruction
is not being used for masking or unmasking of interrupts
. In such a case, the LS 3bits of the Accumulator are not having any useful information. If MSE bit = 1, the SIM instruction is used for masking or unmasking of interrupts.
What is the function of RIM?
The rim is a cylindrical wheel outer edge holding the tire on the wheel. Main function of the rim is
supporting and sealing the tire to the wheel
. The rim ensures proper fitting between tire and rim and retaining the air inside the tubeless tire.
What is true microprocessor?
(a)
Microprocessor contains the essential elements of a computer
, while microcontroller does not. (b) Microcontroller contains the essential elements of a computer, while microprocessor does not. (c) A microprocessor contains the essential elements of a computer, which are fabricated generally on a single IC.
What is LDA microprocessor?
In 8085 Instruction set, LDA is a mnemonic that stands for
LoaD Accumulator with the contents from memory
. In this instructionAccumulatorwill get initialized with 8-bit content from the 16-bit memory address as indicated in the instruction as a16. This instruction uses absolute addressing for specifying the data.
Which one is not a non vector interrupts?
INTR
is the only non-vectored interrupt in 8085 microprocessor. Maskable Interrupts are those which can be disabled or ignored by the microprocessor.
What is the meaning of Jnz instruction?
In 8085 Instruction set, we are having one mnemonic JNZ a16, which stands for “
Jump if Not Zero”
and “a16” stands for any 16-bit address. This instruction is used to jump to the address a16 as provided in the instruction. But as it is a conditional jump so it will happen if and only if the present zero flag value is 0.
What is the function of SID pin in microprocessor?
SID (Serial input data line) − The data on this
line is loaded into accumulator whenever a RIM instruction is executed
.
Which interrupt has the highest priority?
Explanation: The Non-Maskable Interrupt input pin has the highest priority among all the external interrupts. Explanation:
TRAP
is the internal interrupt that has highest priority among all the interrupts except the Divide By Zero (Type 0) exception.
What are 5 types of instruction operations?
- Data handling and memory operations.
- Arithmetic and logic operations.
- Control flow operations.
- Coprocessor instructions.
- Number of operands.
What is the example of instruction?
The definition of instruction is the act of educating, giving the steps that must be followed or an order. An example of instruction is
someone giving another person detailed directions to the library
.
What are the types of instruction?
- Arithmetic Instructions.
- Branch Instructions.
- Data Transfer Instructions.
- Logic Instructions.
- Bit-oriented Instructions.
