LPC11U2x
32-bit ARM Cortex-M0 microcontroller
7.6 Nested Vectored Interrupt Controller (NVIC)
The Nested Vectored Interrupt Controller (NVIC) is part of the Cortex-M0. The tight
coupling to the CPU allows for low interrupt latency and efficient processing of late arriving
interrupts.
7.6.1 Features
Controls system exceptions and peripheral interrupts.
In the LPC11U2x, the NVIC supports 24 vectored interrupts.
