- * Interrupt handler, for application-managed interrupts.
- * When an interrupt occurs, it is automatically disabled.
- * See A_WMAC_INTR_ATTACH() and A_MBOX_INTR_ATTACH().
- *
- * If a handler returns A_HANDLER_DONE, the interrupt is
- * re-enabled. The OS calls the handler next time service
- * is required. This is the normal case for a handler.
- *
- * If a handler returns A_HANDLER_YIELD, the interrupt
- * remains masked. The handler is called again when
- * it is "convenient". This gives the OS an opportunity
- * to run other code/handlers. A handler should return
- * A_HANDLER_YIELD if it might dominate the CPU for too
- * long.
- *
- * If a handler returns A_HANDLER_NOENABLE, the interrupt
- * remains disabled. It is up to the application to re-enable
- * the interrupt (via A_*_INTR_UNMASK) when it's appropriate.
- *
- * Note that many combinations of interrupt functions and
- * interrupt vectors are NOT supported: Callers should use
- * only the macros defined in cmnos_api.h to access the
- * interrupt API.
