WebAVR Interrupt Vectors. Below are tables of the interrupts available on the AVR microcontrollers used in class. The vector name is the identifier that should be used at the start of the the interrupt service routine (ISR). For example, the ISR for the ATmega328P Pin Change Interrupt Request 0 would look like this. Note: The names of the vectors ... WebVector Table . The Vector Table defines the entry addresses of the processor exceptions and the device specific interrupts. It is typically located at the beginning of the program memory, however Using Interrupt Vector Remap it can be relocated to RAM.

This information can be about the source of the interrupts, ISR … WebAn interrupt service routine (ISR) is a software routine that hardware invokes in response to an interrupt. ISR examines an interrupt and determines how to handle it executes the handling, and then returns a logical interrupt value. If no further handling is required the ISR notifies the kernel with a return value. WebA vectored interrupt system employs separate connections for each device so that the computer can give automatic resolution.

WebIf a high-priority exception interrupt is required during exception processing, then the NVIC block: 1) Suspends the exception being processed 2) Starts high-priority exception processing 3) Completes high priority exception processing 4) Resumes interrupted exception processing. It can control the nest, i.e. the exception interrupt processing. WebJul 30, 2015 · Further be aware that the interrupt functions typically need to be declared with a compiler specific keyword or pragma to make sure that the compiler generates correct code. This is because function call and return handling is often different when calling an interrupt vector to when calling a normal function.
