ek-lm4f120xl TI Stellaris LaunchPad 例程之中断实验-This example application demonstrates the interrupt preemption and
tail-chaining capabilities of Cortex-M4 microprocessor and NVIC. Nested
interrupts are synthesized when the interrupts have the same priority,
increasing priorities, and decreasing priorities. With increasing
priorities, preemption will occur in the other two cases tail-chaining
will occur. The currently pending interrupts and the currently executing
interrupt will be displayed on the display GPIO pins E1, E2 and E3 will
be asserted upon interrupt handler entry and de-asserted before interrupt
handler exit so that the off-to-on time can be observed with a scope or
logic analyzer to see the speed of tail-chaining (for the two cases where
tail-chaining is occurring).
