+ * $Header$
+ *
+ * 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
+ *
+ *
+ * 26Sep01 (DJK) The memory map is changed and the device interrupts are
+ * now memory-mapped.
+ *
+ * 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.)
+ *
+ * 27Jul02 (DJK) Fixed the address for the interrupt mask register. Old
+ * documentation stated the port address as 0x140, but
+ * the implementation uses 0x13c.
+ *
+ * 30Jul02 (DJK) Added support for printf. This only supports output to
+ * stderr and stdout. Using the message box interface,
+ * a (newly defined) message or series of messages is
+ * passed to the controller to output bytes as text to
+ * the debug console. These messages are constructed in
+ * the interrupt handler for the SI instruction.
+ * With this implementation, the user is unable to
+ * utilize the message box interface in applications as
+ * specialized interrupt handlers for the external
+ * interrupts are necessary.
