Abstract
It is desirable for interrupt handling routines to be aware of the interrupt latency—the time between a interrupt request is received and the time when the interrupt service routine begins executing. A method is shown wherein the latency is measured by a dedicated counter and is available to the interrupt service routine. Alternately, a threshold may be set indicating the maximum acceptable latency and the interrupt service routine is signaled when said maximum is reached.
