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.
