| 22 | * _Internal_error_Occurred |
---|
| 23 | * |
---|
| 24 | * This routine will invoke the fatal error handler supplied by the user |
---|
| 25 | * followed by the the default one provided by the executive. The default |
---|
| 26 | * error handler assumes no hardware is present to help inform the user |
---|
| 27 | * of the problem. Halt stores the error code in a known register, |
---|
| 28 | * disables interrupts, and halts the CPU. If the CPU does not have a |
---|
| 29 | * halt instruction, it will loop to itself. |
---|
| 30 | * |
---|
| 31 | * Input parameters: |
---|
| 32 | * the_source - what subsystem the error originated in |
---|
| 33 | * is_internal - if the error was internally generated |
---|
| 34 | * the_error - fatal error status code |
---|
| 35 | * |
---|
| 36 | * Output parameters: |
---|
| 37 | * As much information as possible is stored in a CPU dependent fashion. |
---|
| 38 | * See the CPU dependent code for more information. |
---|
| 39 | * |
---|
| 40 | * NOTE: The the_error is not necessarily a directive status code. |
