NMI

Cannot be stopped or preempted by any exception but reset.

Asynchronous.

Hard Fault

All classes of fault, when the fault cannot activate because of priority

or the Configurable Fault handler has been disabled. Synchronous.

Memory Fault

MPU mismatch, including access violation and no match.

Synchronous.

Bus Fault

Pre-fetch, memory access, and other address/memory-related faults.

Synchronous when precise and asynchronous when imprecise.

Usage Fault

Usage fault, such as 'undefined instruction executed' or 'illegal state

transition attempt'. Synchronous.

7-10

Reserved.

SVCall

System service call with SVC instruction. Synchronous.

Debug Monitor

Debug monitor, when not halting. Synchronous, but only active when

enabled. It does not activate if lower priority than the current

activation.

Reserved.

PendSV

Pendable request for system service. Asynchronous and only pended

by software.

SysTick

System tick timer has fired. Asynchronous.
