Description
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
fed through the NVIC (prioritized). These are all
asynchronous. Table 4-2 lists the interrupts on the
LM3S101 controller.
