Interrupts are asynchronous **hardware signals** that can be handled in software. They are handled by the CPU immediately, therefore **interrupting** whatever was being executed before the interrupt.
Interrupts are asynchronous **hardware signals** that can be handled in software. They are handled by the microcontroller immediately, therefore **interrupting** whatever was being executed before the interrupt.
Interrupts can be generated by different events, such as exceptions, timer counter overflows, incoming messages on a bus, GPIO level change etc... All these events generate an Interrupt REQuest (IRQ), which is managed in software by the corresponding IRQHandler().
