hah, I wish. The ARM7 has seven "exception" vectors -- that's it.
0x00 = RESET 0x04 = Undefined instruction 0x08 = Software interrupt (SWI instruction, used to escape the restricted USR cpu mode) 0x0C = Data abort (a very very very much lesser form of an access violation; accessing memory that's physically not there) 0x10 = Prefetch abort (a data abort that happens trying to read the next instruction) 0x14 = IRQ <- these two can't really even count as exceptions! 0x18 = FIQ <- which makes for five... 0x1C = <- 0x20 = <- Oh, yeah, and two "reserved" fields which aren't likely to ever be used.
Anyway, this is a bit off-topic now.
