4853 + * DESCRIPTION: shared typedef's, constants and API for TNETD73xx
4854 + *
4855 + * REVISION HISTORY:
4856 + * 27 Nov 02 - PSP TII

4861 +/*
4862 + *
4863 + *
4864 + * These are const, typedef, and api definitions for tnetd73xx.
4865 + *
4866 + * NOTES:
4867 + * 1. This file may be included into both C and Assembly files.
4868 + * - for .s files, please do #define _ASMLANGUAGE in your ASM file to
4869 + * avoid C data types (typedefs) below;
4870 + * - for .c files, you don't have to do anything special.
4871 + *
4872 + * 2. This file has a number of sections for each SOC subsystem. When adding
4873 + * a new constant, find the subsystem you are working on and follow the
4874 + * name pattern. If you are adding another typedef for your interface, please,
4875 + * place it with other typedefs and function prototypes.
4876 + *
4877 + * 3. Please, DO NOT add any macros or types that are local to a subsystem to avoid
4878 + * cluttering. Include such items directly into the module's .c file or have a
4879 + * local .h file to pass data between smaller modules. This file defines only
4880 + * shared items.
