2.4.2 Exception Stacking Order
Exception processing saves the most volatile portion of the current processor context on top
of the supervisor stack. This context is organized in a format called the exception stack
frame. The amount and type of information saved on the stack is determined by the type of
exception. The reset exception causes the M68000 to halt current execution and to read a
new SSP and PC as shown in Table 2-5. A bus error or address error causes the M68000
to store the information shown in Figure 2-3. The interrupts, traps, illegal instructions, and
trace stack frames are shown in Figure 2-4.

NOTES:
1. Vector numbers 12–14, 16–23, and 48–63 are reserved for future enhancements by Motorola
2. Unlike the other vectors which only require two words, reset vector (0) requires four words and is
3. The spurious interrupt vector is taken when there is a bus error indication during interrupt
