settable
-
Usage fault, such as undefined instruction executed
or illegal state transition attempt. This is
synchronous.
Reserved.
SVCall
11
settable System service call with SVC instruction. This is
synchronous.
Debug Monitor
12
settable 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.
PendSV
14
settable Pendable request for system service. This is
asynchronous and only pended by software.
SysTick
15
settable System tick timer has fired. This is asynchronous.
Interrupts

settable
Asserted from outside the ARM Cortex-M3 core and
fed through the NVIC (prioritized). These are all
asynchronous. Table 4-2 lists the interrupts on the
LM3S613 controller.
