+
+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).
