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 D0, D1 and D2 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). + +------------------------------------------------------------------------------- + +Copyright (c) 2011-2014 Texas Instruments Incorporated.
