*
* 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,
* _DEV3IVEC, _DEV4IVEC, _DEV5IVEC, _DEV6IVEC, _DEV7IVEC
*
* 28Apr05 (DJK) Added support for the overflow vector.
*
* XXXXXXX (DJK) Modified for the MS2 target
*
* 09Jan04 (DJK) Modified internal I/O port definitions for the
* MS1-16-003.
*
* 10Oct01 (DJK) The memory map is finalized and the first 4K of address
* space is now reserved for memory-mapped I/O devices.
* (There is over 2K unused, reserved space in this area.)
*
* 26Sep01 (DJK) The memory map is changed and the device interrupts are
* now memory-mapped.
