What is interrupts and list classes of interrupts in operating system?
An interrupt is an event that alters the sequence in which the processor execute instructions. It is generated by hardware of computer system. Classes of interrupt:- IBM processor has six types of interrupts. * svc interrupt(supervisor call) *input/output interrupts *external interrupts *Restart interrupts *Program check interrupt *Machine check interrupts
Which interrupts has lowest priority?
In a typical interrupt priority scheme, the lowest priority interrupts are often referred to as "low-priority" or "background" interrupts, such as timer interrupts or non-critical peripheral interrupts. These interrupts are usually masked or delayed in favor of higher-priority interrupts that require immediate attention. Consequently, when a high-priority interrupt occurs, the low-priority interrupts may be temporarily ignored until the system has handled more urgent tasks.
No of interrupts of 8051 excluding reset?
1.The excluding interrupts are INT0 & INT1 2.The Timer0 and Timer1 are interrupts are generated by TF0 and TF1
How do you dump any program code on micro controller 89c51?
In order to dump any program code onto a micro controller for a 89c51, you would first have to find access to the main controller board of the item, and plug the program code directly into that.
What is other name of 89c51?
The 89C51 is also known as the AT89C51, which refers to a specific microcontroller from Atmel (now part of Microchip Technology). It is an 8-bit microcontroller based on the Intel 8051 architecture and is commonly used in embedded systems for various applications.
Different between maskable and non-maskable interrupt?
Maskable interrupts trigger events are not always important and so the programmer can decide that the event should not cause a program to jump. Nonmaskable interrupts can not be ignored by the programmer and therefore they have absolute priority.
