+@chapter Default Fatal Error Processing
+@section Introduction
+Upon detection of a fatal error by either the
+application or RTEMS the fatal error manager is invoked. The
+fatal error manager will invoke the user-supplied fatal error
+handlers. If no user-supplied handlers are configured, the
+RTEMS provided default fatal error handler is invoked. If the
+user-supplied fatal error handlers return to the executive the
+default fatal error handler is then invoked. This chapter
+describes the precise operations of the default fatal error
+@section Default Fatal Error Handler Operations
+The default fatal error handler which is invoked by
+the @code{rtems_fatal_error_occurred} directive when there is
+no user handler configured or the user handler returns control to
+RTEMS. The default fatal error handler disables processor interrupts,
+places the error code in @b{XXX}, and executes a @code{XXX}
+instruction to simulate a halt processor instruction.
