| 9 | @chapter Default Fatal Error Processing |

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