+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 UART; GPIO pins B3, L1 and L0 (the
+GPIO on jumper J27 on the left edge of the board) 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).
