1 interrupt
= INT1) прерываниемеханизм, реализуемый в виде посылаемых центральному процессору специальных сигналов и микропрограмм, позволяющий ему реагировать на события внешнего мира (изменение состояния системы или самого ЦП) или особые состояния исполняемой в данный момент программы. Можно сказать, что прерывание - асинхронное внешнее или внутреннее событие, требующее от ЦП обслуживания, - оно может произойти во время исполнения машинной команды, до его начала или после завершения исполнения (см. instruction cycle). Прерывание, если оно принято процессором, вызывает прекращение обработки текущей программы, сохранение в стеке состояния процессора и регистров и передачу управления специальной программе обработки конкретного вида прерывания (ISR). По завершении обработки происходит восстановление состояния регистров и процессора и управление обычно возвращается прерванной программе. Существуют различные классы прерываний: аппаратные (hardware interrupt), программные (software interrupt), ввода-вывода (от дисководов, клавиатуры, последовательного порта, мыши и т. д.) и от таймера (timer interrupt). Различают прерывания маскируемые (maskable interrupt) и немаскируемые (nonmaskable interrupt), в зависимости от того, может ли быть отложено обслуживание конкретного вида прерываний. Например, нельзя маскировать прерывания по исчезновению питания и сбросу системы. Для ввода сигнала прерывания в процессор у него имеется один или несколько специализированных выводов (ножек), кроме того, схемы, формирующие сигнал прерывания могут выставлять на шине данных номер прерывания. Конкретная реализация системы прерываний - составная часть архитектуры процессора.Interrupts allow the microcontroller to interact with its environment. — Прерывания позволяют микроконтроллеру взаимодействовать со окружающим его оборудованием см. тж. clock interrupt, context switching, error interrupt, external interrupt, idle interrupt, internal interrupt, interprocessor interrupt, interrupt acknowledge, interrupt condition, interrupt controller, interrupt disable, interrupt dispatcher, interrupt-driven, interrupt enable, interrupt event, interrupt flag, interrupt handler, interrupt input, interrupt latency, interrupt level, interrupt line, interrupt list, interrupt mask, interrupt number, interrupt priority, interrupt response, interrupt source, interrupt trap, interrupt vector, INTR, I/O interrupt, IRET, IRQ, missed interrupt, multiple interrupts, nested interrupt, pending interrupt, vectored interrupt
