User Interrupt Vectors
—
NOTES:
1. Vector numbers 12, 13, 16–23, and 48–63 are reserved for future
enhancements by Motorola. No user peripheral devices should be
assigned these numbers.
2. Reset vector (0) requires four words, unlike the other vectors which only
require two words, and is located in the supervisor program space.
3. The spurious interrupt vector is taken when there is a bus error
indication during interrupt processing.
4. TRAP #n uses vector number 32+ n.
5. MC68010 only. This vector is unassigned, reserved on the MC68000
and MC68008.
6. SP denotes supervisor program space, and SD denotes
supervisor data space.
