What are the level triggering interrupts?
A level-triggered interrupt is requested by holding the interrupt signal at its particular (high or low) active logic level.
A device invokes a level-triggered interrupt by driving the signal to and holding it at the active level..
What does interrupt mean?
to cause or make a break in the continuity or uniformity of (a course, process, condition, etc.). to break off or cause to cease, as in the middle of something: He interrupted his work to answer the bell.
Which one of the following interrupt is only level triggering?
Which one of the following interrupt/interrupts is/are only level triggering? TRAP is edge as well as level triggered.
Which stack is used in 8085?
LIFOAnswer: LIFO (Last In First Out) stack is used in 8085.In this type of Stack the last stored information can be retrieved first.
Which of the following interrupt has second 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.
Which interrupt has highest priority in 8086?
(A) NMI (Non Maskable Interrupt) – It is a single pin non maskable hardware interrupt which cannot be disabled. It is the highest priority interrupt in 8086 microprocessor. After its execution, this interrupt generates a TYPE 2 interrupt.
Which interrupt is Unmaskable?
INTR, RST 7.5, RST 6.5, RST 5.5 are maskable interrupts in 8085 microprocessor. Non-Maskable Interrupts are those which cannot be disabled or ignored by microprocessor. TRAP is a non-maskable interrupt. It consists of both level as well as edge triggering and is used in critical power failure conditions.
What is the basic advantage of priority interrupt?
A priority interrupt is a system which decides the priority at which various devices, which generates the interrupt signal at the same time, will be serviced by the CPU. The system has authority to decide which conditions are allowed to interrupt the CPU, while some other interrupt is being serviced.
What is interrupt and ISR?
Stands for “Interrupt Service Routine.” An ISR (also called an interrupt handler) is a software process invoked by an interrupt request from a hardware device. It handles the request and sends it to the CPU, interrupting the active process. When the ISR is complete, the process is resumed.
Which is the interrupt having highest priority?
TRAPTRAP is the internal interrupt that has the highest priority among all interrupts except the divide by zero exception.
What is interrupt priority in microprocessor?
The 8085 microprocessor has five interrupt inputs. … These interrupts have a fixed priority of interrupt service. If two or more interrupts go high at the same time, the 8085 will service them on priority basis. The TRAP has the highest priority followed by RST 7.5, RST 6.5, RST 5.5.
What is interrupt and its types?
Hardware interrupts can be classified into two types they are. Maskable Interrupt: The hardware interrupts which can be delayed when a much highest priority interrupt has occurred to the processor. Non Maskable Interrupt: The hardware which cannot be delayed and should process by the processor immediately.
