// This macro defines xxDebugOut where xx is the component prefix
// to be defined. This declares a static variable 'xxInfoLevel', which
// can be used to control the type of xxDebugOut messages printed to
// the terminal. For example, xxInfoLevel may be set at the debug terminal.
// This will enable the user to turn debugging messages on or off, based
// on the type desired. The predefined types are defined below. Component
// specific values should use the upper 24 bits
//
// To Use:
//
// 1) In your components main include file, include the line
// DECLARE_DEBUG(comp)
// where comp is your component prefix
//
// 2) In one of your components source files, include the line
// DECLARE_INFOLEVEL(comp)
// where comp is your component prefix. This will define the
// global variable that will control output.
//
// It is suggested that any component define bits be combined with
// existing bits. For example, if you had a specific error path that you
// wanted, you might define DEB_<comp>_ERRORxxx as being
//
// (0x100 | DEB_ERROR)
//
// This way, we can turn on DEB_ERROR and get the error, or just 0x100
// and get only your error.
