0x00000004	Undefined Instruction	Undefined	NewtonOS uses this interrupt to emulate floating point operations that are not available on the SA-110
0x00000008	Software Interrupt	Supervisor	all important operating System calls go through this interrupt
0x0000000C	Abort Prefetch	Abort	the Abort interrupts work together with the MMU to provide runtime decompression and virtual memory
0x00000010	Abort Data	Abort
0x00000014	unused
0x00000018	IRQ	IRQ	NewtonOS can assign tasks to the following two interrupts; they are also used for task switching
