    77ALMOS-MK identifies a peripheral by a composite index (func,impl). The '''func''' index defines a functionnal type, the '''impl''' index defines a specific hardware implementation.
    8  * Each value of the functional index defines a generic (implementation independent) device XYZ, that is characterized by a specific API defined in the ''dev_xyz.h'' file). This generic API allows the kernel to access the peripheral without taking care on the actual implementation.

    99 * For each generic device XYZ, it can exist several hardware implementation, and each value of the implementation index '''impl''' is associated with a specific driver, that must implement
