| 1. | EOIs may indicate the interrupt vector implicitly, or explicitly.
|
| 2. | Other well-known examples are the interrupt vector table and the main loop.
|
| 3. | Interrupts are not dispatched through interrupt vectors, as with nearly all other Freescale processors.
|
| 4. | At boot time, all BIOS services are available, and the memory below address 0x00400 contains the interrupt vector table.
|
| 5. | By doing so the console ROM can be copied into RAM, and thus things like interrupt vectors and such could be modified.
|
| 6. | Alternatively on systems using the shared library concept, the interrupt vector table or the import descriptor table can be modified in memory.
|
| 7. | An input / output device determined the memory addresses to which it would respond, and specified its own interrupt vector and interrupt priority.
|
| 8. | This procedure of installing ISRs is called " chaining " or " hooking " an interrupt or an interrupt vector.
|
| 9. | The " predefined " method loads the program counter ( PC ) directly with the address of some entry inside the interrupt vector table.
|
| 10. | The " exception table " ( interrupt vector table interrupt vector addresses ) is fixed at addresses 0 through 1023, permitting 256 32-bit vectors.
