Module Name:

    htdebug.h


Abstract:

    This module contains all the debug definitions


Author:
    23-Apr-1992 Thu 20:01:55 updated  -by-  Daniel Chou (danielc)
        changed DBG_TIMEx structure fields' 'CHAR' type to 'BYTE' type, this
        will make sure if compiled under MIPS the default 'unsigned char' will
        not affect the signed operation on the single 8 bits

    28-Mar-1992 Sat 20:54:09 updated  -by-  Daniel Chou (danielc)
        change DEF_DBGPVAR() marco so MIPS build does not complaint
