    77ALMOS-MKH identifies a peripheral by a composite index (func,impl). The '''func''' index defines a functional type, the '''impl''' index defines a specific hardware implementation.
    8  * Each value of the functional index '''func''' defines a generic (implementation independent) device, that is characterized by a specific. This API allows the kernel to access the peripheral without taking care on the actual hardware implementation. 
    9  * For each generic device ''func'', it can exist several hardware implementation, and each value of the implementation index '''impl''' is associated with a specific driver, that must implement the API defined for the ''func'' device.
