The NVIC includes a non-maskable interrupt (NMI), and provides up to 256 interrupt priority levels. It provides examples of interrupt sources for Cortex-M0+ and the basic questions to consider when implementing interrupt-driven programs. An interrupt is a hardware or software signal that causes the CPU to suspend the current program and execute a specific handler routine called an ISR.
