+@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 is 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
+handler.

+@section Default Fatal Error Handler Operations
+
+The default fatal error handler which is invoked by
+the 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 to
+level 31, places the error code in G0, and executes a branch to
+self instruction to simulate a halt processor instruction.
