| 4 | * interrupt_vectors.s -- the interrupt handler jump table. |
---|
| 5 | * |
---|
| 6 | * |
---|
| 7 | * There are a total of 32 interrupt vector possible, however, only |
---|
| 8 | * 11 of those are currently used (the others are reserved). The |
---|
| 9 | * order of vectors is as follows: |
---|
| 10 | * |
---|
| 11 | * 1. Boot Vector. Vector for power-on/reset. |
---|
| 12 | * 2. Software Vector. Vector for handling the SI instruction (an |
---|
| 13 | * explicit interrupt caused by software). |
---|
| 14 | * 3. Break Vector. Vector for handling the Break instruction. |
---|
| 15 | * 4. Device 0 Vector. Service vector for device zero. |
---|
| 16 | * 5. Device 1 Vector. Service vector for device one. |
---|
| 17 | * 6. Device 2 Vector. Service vector for device two. |
---|
| 18 | * 7. Device 3 Vector. Service vector for device three. |
---|
| 19 | * 8. Device 4 Vector. Service vector for device four. |
---|
| 20 | * 9. Device 5 Vector. Service vector for device five. |
---|
| 21 | * 10. Device 6 Vector. Service vector for device six. |
---|
| 22 | * 11. Device 7 Vector. Service vector for device seven. |
---|
| 23 | * |
---|
| 24 | * The rest of the interrupt vectors are reserved for future use. |
---|
| 25 | * |
---|
| 26 | * |
---|
| 27 | * Each jump table entry consists of the following two instructions: |
---|
| 28 | * |
---|
| 29 | * jmp Label ; Label as appropriate |
---|
| 30 | * nop ; implemented as or r0,r0,r0 |
---|
| 31 | * |
---|
| 32 | * The following labels are reserved for the vectors named above, |
---|
| 33 | * respectively: |
---|
| 34 | * |
---|
| 35 | * _BOOTIVEC, _SOFTIVEC, _BRKIVEC, _DEV0IVEC, _DEV1IVEC, _DEV2IVEC, |
---|
| 36 | * _DEV3IVEC, _DEV4IVEC, _DEV5IVEC, _DEV6IVEC, _DEV7IVEC |
---|
| 37 | * |
---|
| 38 | * 09Jan04 (DJK) Modified internal I/O port definitions for the |
---|
| 39 | * MS1-16-003. |
---|
| 40 | * |
---|
| 41 | * 10Oct01 (DJK) The memory map is finalized and the first 4K of address |
---|
| 42 | * space is now reserved for memory-mapped I/O devices. |
---|
| 43 | * (There is over 2K unused, reserved space in this area.) |
---|
| 44 | * |
---|
| 45 | * 26Sep01 (DJK) The memory map is changed and the device interrupts are |
---|
| 46 | * now memory-mapped. |
