 Each entry in one interrupt vector array contains an extended pointer on the device descriptor that is the "source" of the interrupt. This device descriptor contains a link to the ISR to be executed to handle the interrupt event. 
 
-As the generic ICU device works for a single client (the local kernel instance), it does not use the device descriptor  queue. All commands are immediately executed, using the device lock to get exclusive access to the ICU device state.
+The ICU peripheral does not execute I/O operations, but is just acting as a dynamically configurable interrupt router for another I/O operation. Therefore, ALMOS-MK does not use the iCU device waiting queue, but calls directly the ICU driver blocking functions.
