Abstract:  

    This file provides definitions for the debug section of the Windows CE P2
    Reference Platform provided by the housekeeping FPGA.  The interfaces that
    are described here are only available on a development platform that is
    compatible with the P2 platform; they are not available on an OEM platform.
