5.2: 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 (i.e. sets the I bit in the PSW register to 0), places the error code in r1, and executes a break instruction to simulate a halt processor instruction.
