Version 2.0

2.3 NESTED VECTORED INTERRUPT CONTROLLER (NVIC)

All interrupts including the core exceptions are managed by the NVIC. NVIC has the following Features:



The NVIC supports 32 vectored interrupts.



4 programmable interrupt priority levels with hardware priority level masking.



Low-latency exception and interrupt handling.



Efficient processing of late arriving interrupts.



Implementation of System Control Registers



Software interrupt generation.
