| 5 | * There are a total of 32 interrupt vector possible, however, only |
---|
| 6 | * 11 of those are currently used (the others are reserved). The |
---|
| 7 | * order of vectors is as follows: |
---|
| 8 | * |
---|
| 9 | * 1. Boot Vector. Vector for power-on/reset. |
---|
| 10 | * 2. Software Vector. Vector for handling the SI instruction (an |
---|
| 11 | * explicit interrupt caused by software). |
---|
| 12 | * 3. Break Vector. Vector for handling the Break instruction. |
---|
| 13 | * 4. Device 0 Vector. Service vector for device zero. |
---|
| 14 | * 5. Device 1 Vector. Service vector for device one. |
---|
| 15 | * 6. Device 2 Vector. Service vector for device two. |
---|
| 16 | * 7. Device 3 Vector. Service vector for device three. |
---|
| 17 | * 8. Device 4 Vector. Service vector for device four. |
---|
| 18 | * 9. Device 5 Vector. Service vector for device five. |
---|
| 19 | * 10. Device 6 Vector. Service vector for device six. |
---|
| 20 | * 11. Device 7 Vector. Service vector for device seven. |
---|
| 21 | * |
---|
| 22 | * The rest of the interrupt vectors are reserved for future use. |
---|
| 23 | * |
---|
| 24 | * |
---|
| 25 | * Each jump table entry consists of the following two instructions: |
---|
| 26 | * |
---|
| 27 | * jmp Label ; Label as appropriate |
