Dropped Interrupts
When multiple interrupts are triggered during the interrupt latency period, it is possible that interrupt
blocks will only be executed one time even though the interrupt trigger has occurred more than once.
The likelihood of this occurring will increase if the system interrupt latency has increased due to the
specific configuration and use of the system.
This will not cause the CPU to miss a given interrupt; just consolidate the number of times an interrupt
block is executed even though the interrupt stimulus had occurred more than one time.
