/**
 * @page cpuimplfss CPU Family Specific Services Implementation Guide
 *
 * CPU Family Specific Services provides access to supported family service functions and data,
 * in a manner that isolates calling code from knowledge about particular families or which
 * families are supported in the current build.
 *
 * @par Adding a Method to Family Specific Services
 *
 * To add a new method to Family Specific Services, follow these steps.
 * <ul>
 * <li> Create a typedef for the Method with the correct parameters and return type.
 *
 *   <ul>
 *   <li> Name the method typedef (*PF_METHOD_NAME)(), where METHOD_NAME is the same name as the method table item,
 *     but with "_"'s and UPPERCASE, rather than mixed case.
 *     @n <tt> typedef VOID (*PF_METHOD_NAME)(); </tt> @n
 *
 *   <li> [Optionally make the type F_<name> and provide a separate:
 *     @n <tt> typedef F_METHOD_NAME *PF_METHOD_NAME> </tt> @n
 *     and provide a single line "///" doxygen comment brief description on the PF_ type.]
 *   </ul>
 *
 * <li> The first parameter to @b all Family Specific Service Methods is @b required to be a reference to
 *   their Family Service struct.
 *   @n <tt> IN       CPU_SPECIFIC_SERVICES *FamilySpecificServices </tt> @n
 *
 * <li> Provide a standard doxygen function preamble for the Method typedef.  Begin the
 *   detailed description by provide a reference to the method instances page by including
 *   the lines below:
 *   @code
 *   *
 *   * @CpuServiceInstances
 *   *
 *   @endcode
 *   @note It is important to provide documentation for the method type, because the method may not
 *   have an implementation in any families supported by the current package. @n
 *
 * <li> Add to the CPU_SPECIFIC_SERVICES struct an item for the Method:
 *   @n <tt>  PF_METHOD_NAME MethodName; ///< Method: description. </tt> @n
 * </ul>
 *
 * @par Implementing a Family Specific Instance of the method.
 *
 * To implement an instance of a method for a specific family follow these steps.
 *
 * - In appropriate files in the family specific directory, implement the method with the return type
 *   and parameters matching the method typedef.
 *
 * - Name the function FnnMethodName(), where nn is the family number.
 *
 * - Create a doxygen function preamble for the method instance.  Begin the detailed description with
 *   an Implements command to reference the method type and add this instance to the Method Instances page.
 *   @code
 *   *
 *   *  @CpuServiceMethod{::F_METHOD_NAME}.
 *   *
 *   @endcode
 *
 * - To access other family specific services as part of the method implementation, the function
 *   @b must use FamilySpecificServices->OtherMethod().  Do not directly call other family specific
 *   routines, because in the table there may be overrides or this routine may be shared by multiple families.
 *
 * - Do @b not call Family translation services from a family specific instance.  Use the parameter.
 *
 * - Add the instance to the family specific CPU_SPECIFIC_SERVICES instance.
 *
 * - If a family does not need an instance of the method use one of the CommonReturns from
 *   CommonReturns.h with the same return type.
 *
 * @par Invoking Family Specific Services.
 *
 * The following example shows how to invoke a family specific method.
 * @n @code
 *        CPU_SPECIFIC_SERVICES *FamilyServices;
 *
 *        GetCpuServicesOfCurrentCore (&FamilyServices, StdHeader);
 *        ASSERT (FamilyServices != NULL);
 *        FamilyServices->MethodName (FamilyServices, StdHeader);
 * @endcode
 *
