      9description:
     10  The IPCC block provides a non blocking signaling mechanism to post and
     11  retrieve messages in an atomic way between two processors.
     12  It provides the signaling for N bidirectionnal channels. The number of
     13  channels (N) can be read from a dedicated register.
