9@chapter Default Fatal Error Processing
10
11@section Introduction
12
13Upon detection of a fatal error by either the
14application or RTEMS the fatal error manager is invoked.  The
15fatal error manager will invoke the user-supplied fatal error
16handlers.  If no user-supplied handlers are configured,  the
17RTEMS provided default fatal error handler is invoked.  If the
18user-supplied fatal error handlers return to the executive the
19default fatal error handler is then invoked.  This chapter
20describes the precise operations of the default fatal error
21handler.
22
23@section Default Fatal Error Handler Operations
24
25The default fatal error handler which is invoked by
26the @code{rtems_fatal_error_occurred} directive when there is
27no user handler configured or the user handler returns control to
28RTEMS.  The default fatal error handler disables processor interrupts,
29places the error code in @b{XXX}, and executes a @code{XXX}
30instruction to simulate a halt processor instruction.
