An interrupt control register, or ICR, is a
hardware register in a
computer chip
An integrated circuit or monolithic integrated circuit (also referred to as an IC, a chip, or a microchip) is a set of electronic circuits on one small flat piece (or "chip") of semiconductor material, usually silicon. Large numbers of tiny ...
used to configure the chip to generate
interrupts—to raise a signal on an interrupt line—in response to some event occurring within the chip or a
circuit
Circuit may refer to:
Science and technology
Electrical engineering
* Electrical circuit, a complete electrical network with a closed-loop giving a return path for current
** Analog circuit, uses continuous signal levels
** Balanced circu ...
connected to the chip.
An Interrupt Control is usually used in Micro controllers to generate interrupts signals which tells the CPU to pause its current task and start executing another set of predefined activities.
