LPC11Cx2/Cx4
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.
• In the LPC11Cx2/Cx4, the NVIC supports 32 vectored interrupts including 13 inputs to
the start logic from individual GPIO pins.
