Interrupts
Exception Type
Position Priority^a Description
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.
-
13
-
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
16 and
above
settable Asserted from outside the ARM Cortex-M3 core and fed through the NVIC
(prioritized). These are all asynchronous. Table 4-2 on page 40 lists the
interrupts on the LM3S1958 controller.
a. 0 is the default priority for all the settable priorities.
