Name of instruction to reset the interrupt?
software interrupts
Highest priority interrupt in micro processor?
The highest priority interrupt in a microprocessor is usually the reset interrupt. When a reset occurs, the microprocessor is forced to stop its current operations and begin executing the reset routine. This is critical for initializing the processor and setting it to a known state before starting normal operations.
What is sim in 8085?
The SIM instruction in the 8085 is Set Interrupt Mask. You can use it to set and clear the three interrupt masks for RST7.5, RST6.5, and RST5.5, as well as to set or clear the SOD (Serial Output Data) pin. You can also reset the pending RST7.5 interrupt, if desired.
What is SIM and RIM instruction in microprocessor?
RIM stands for read interrupt mask and SIM stands for set interrupt mask.The SIM instruction is used to copy the contents of the accumulator into the interrupt mask.The RIM instruction is used to interpret the RST interrupt positions.
What is the two interrupt?
The first is the real interrupt, when the external hardware interrupts the processors' work;the second is the exception, like page fault or division by zero;the third is the supervisor call (SVC) which is sometimes called interrupt (or 'software interrupt') as well.
What does interrupt?
Well if somone farted or sneezed comone sence.
When microprocessor encounters HALT instruction what it do?
It floats the address and data buses, and enters THALT state, until an interrupt or reset occurs.
Is it rude to interrupt someone while they are speaking"?
Yes, it is generally considered rude to interrupt someone while they are speaking. It is important to listen and wait for your turn to speak in a conversation.
What is a non-maskable?
A non-maskable interrupt is an interrupt that cannot be blocked, or masked, by the processor. In the 8085, TRAP is such an interrupt. If TRAP goes high and stays high, an interrupt vector sequence at address 24H will occur, and there is nothing the processor can do to prevent that.However, external hardware can accomplish the same thing. In a project that I designed, I needed a fourth single pin interrupt beyond RST5.5, RST6.5, and RST7.5, but I needed it to be maskable, so I built a flip flop in hardware that I could set or reset which would be AND'ed with the interrupt request to generate a maskable TRAP.
What is a NMI error?
It's a Non Maskable Interrupt. It is an interrupt to a computer system that cannot be ignored (can't be masked). For example; when you push the reset button on the PC front panel you are performing an NMI. All services will be interrupted to perform a system boot.
Use interrupt in a sentence?
Let me interrupt you there! Well I'ma let you finish, I don't mean to interrupt, but Beyonce did have the best video in the entire world. I can interrupt him if you like, but he gets very angry when he's disturbed from his work.
Why there is a need for disabling interrupts in 8085?
Interrupt are automatically disabled on interrupt entry (except for TRAP, which is non-maskable) so that interrupts do not, by default, nest. You would also disable enterrupts surrounding a critical section of code that, perhaps, manipulated an interrupt register. It is possible to re-enable interrupts during an interrupt service routine. Typically, you would have a hierarchy, such as RST7.5, then RST 6.5, then RST 5.5. Initially, at interrupt entry, all interrupts are disabled. You could then manipulate the interrupt mask using the RIM and SIM instructions and enable further interrupts, allowing a nested architecture. At interrupt exit, then, you would disable interrupts, reset the mask, enable interrupts, and return from interrupt.
