Nested Vectored Interrupt Controller
NVIC enables efficient exception handling
The NVIC includes support for
Fully deterministic exception handling timing behavior
Everything can be written in C
– Integrated within the processor - closely coupled with the core
– Handles system exceptions & interrupts
– Prioritization of exceptions
– Tail-chaining & Late arriving interrupts
– Always takes the same number of cycles to handle an exception
– Fixed at 16 clocks for no jitter
– Register to trade off latency versus jitter
