    LPC122x
    32-bit ARM Cortex-M0 microcontroller
    7.5 Nested Vectored Interrupt Controller (NVIC)
    The Nested Vectored Interrupt Controller (NVIC) is an integral part of the Cortex-M0. The
    tight coupling to the CPU allows for low interrupt latency and efficient processing of late
    arriving interrupts.
    7.5.1 Features
    Controls system exceptions and peripheral interrupts.
