/*
 *
 * 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.
