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.
