Stellaris Luminary Micro 系列之 DK-LM3S310 多个学习范例全都是基于 Keil 工程版的范例, 而范例内容列举如下: 1.BitBand 2.Comparator

Interrupts

This example application demonstrates the interrupt preemption and
tail-chaining capabilities of Cortex-M3 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 LCD; individual LEDs connected to port B0-B2 will be turned on
upon interrupt handler entry and off 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).

In order for this example to work properly, the ULED0 (JP22), ULED1 (JP23), and
ULED2 (JP24) jumpers must be installed on the board, and the PB1 (JP1) jumper
on the daughtercard must be set to pins 2 & 3.
