Preliminary
Description
Pre-fetch fault, memory access fault, and other address/memory related
faults. This is synchronous when precise and asynchronous when
imprecise.
You can enable or disable this fault.
Usage fault, such as undefined instruction executed or illegal state
transition attempt. This is synchronous.
Reserved.
System service call with SVC instruction. This is synchronous.
Debug monitor (when not halting). This is synchronous, but only active
when enabled. It does not activate if lower priority than the current
activation.
Reserved.
Pendable request for system service. This is asynchronous and only
pended by software.
System tick timer has fired. This is asynchronous.
Asserted from outside the ARM Cortex-M3 core and fed through the
NVIC (prioritized). These are all asynchronous. Table 4-2 on page 48
lists the interrupts on the LM3S6950 controller.
