* interrupt_vectors.s -- the interrupt handler jump table.
|
|
*
|
|
*
|
|
* There are a total of 32 interrupt vector possible, however, only
|
|
* 11 of those are currently used (the others are reserved). The
|
|
* order of vectors is as follows:
|
|
*
|
|
* 1. Boot Vector. Vector for power-on/reset.
|
|
* 2. Software Vector. Vector for handling the SI instruction (an
|
|
* explicit interrupt caused by software).
|
|
* 3. Break Vector. Vector for handling the Break instruction.
|
|
* 4. Device 0 Vector. Service vector for device zero.
|
|
* 5. Device 1 Vector. Service vector for device one.
|
|
* 6. Device 2 Vector. Service vector for device two.
|
|
* 7. Device 3 Vector. Service vector for device three.
|
|
* 8. Device 4 Vector. Service vector for device four.
|
|
* 9. Device 5 Vector. Service vector for device five.
|
|
* 10. Device 6 Vector. Service vector for device six.
|
|
* 11. Device 7 Vector. Service vector for device seven.
|
|
*
|
|
* The rest of the interrupt vectors are reserved for future use.
|
|
*
|
|
*
|
|
* Each jump table entry consists of the following two instructions:
|
|
*
|
|
* jmp Label ; Label as appropriate
|
|
* nop ; implemented as or r0,r0,r0
|
|
*
|
|
* The following labels are reserved for the vectors named above,
|
|
* respectively:
|
|
*
|
|
* _BOOTIVEC, _SOFTIVEC, _BRKIVEC, _DEV0IVEC, _DEV1IVEC, _DEV2IVEC,
