Interrupt control and state register

An interrupt control register, or ICR, is a hardware register in a computer chip 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 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. WebFeb 19, 2014 · With pin change interrupts, you'll have to keep track of the last state of the active pins, and compare it with their new state in order to determine which pin(s) changed. Read the pins; Store their current state; When the interrupt happens, compare the previous value to the new value. Determine which pins changed, and how they changed
