LPC1311/13/42/43

32-bit ARM Cortex-M3 microcontroller

7.6 Nested Vectored Interrupt Controller (NVIC)

The Nested Vectored Interrupt Controller (NVIC) is an integral part of the Cortex-M3. 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.

• On the LPC1311/13/42/43, the NVIC supports 16 vectored interrupts. In addition, up

to 40 of the individual GPIO inputs are NVIC-vector capable.
