+//! the interrupt handler (as opposed to the very last action) to avoid
+//! returning from the interrupt handler before the interrupt source is
+//! actually cleared.  Failure to do so may result in the interrupt handler
+//! being immediately reentered (since NVIC still sees the interrupt source
