@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

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 7, places the error code in D0, and executes a stop

instruction to simulate a halt processor instruction.
