          Flash Programming Plug-In for Lauterbach JTAG/ICD TRACE32

GENERAL DESCRIPTION

  This header file contains the structures that are used to communicate 
  between our plug-in and Lauterbach TRACE32 Debugger. Also contains
  definitions for commands and responses that the JTAG ICD understands.
