The SIM and RIM instructions in the 8085 microprocessor are used to set (SIM) and read (RIM) the interrupt mask. With SIM, you can mask or unmask RST5.5, RST6.5, and RST7.5, you can reset the pending RST7.5 flip flop, and you can set or reset the SOD (Serial Output Data) pin.

Different beetwen sim and rim?
SIM stands for “Set Interrupt Mask” It is 1 byte instruction RIM stands for “Read Interrupt Mask” it is 1 byte MULTI-PURPOSE instruction.
Instruction that are present in 8085 and not in 8080?
RIM, SIM, RST, to name three.
Can a program written in 8085 microprocessor run in 8086 microprocessor?
No. They have a different instruction set. However, the processors are sufficiently similar that an 8086 assembler could assemble an 8085 program, given appropriate constants and macros. Some things, however, such as RIM, SIM, RST, etc. do not have equivalents in the 8086.
What happens after the microprocessor completes an instruction?
It fetches the next instruction.
Which group of instruction do not affected the flag in microprocessor?
branch instruction
When the microprocessor completes an instruction what happens?
it goes to queue for next instruction
What is the purpose of RST instruction in microprocessor?
Special restart instruction used with interrupts
What instruction is executed by the x86-64 microprocessor?
it has an instruction set of a few hundred instructions.
What is the need of Instruction PointerIP in 8086 microprocessor?
The Instruction Pointer (IP) in an 8086 microprocessor contains the address of the next instruction to be executed. The processor uses IP to request memory data from the Bus Interface Unit, and then increments it by the size of the instruction.
What is DAD RP instruction in microprocessor?
A=HL+A or A=DE+A
What is 1 byte instruction in microprocessor?
1byte instruction = MOV A,B 2byte instruction = MVI A,01H 3byte instruction = STA 2030H
Which instruction in 8086 microprocessor is 6 bytes long?
mov
