interrupts
To reduce external logic and simplify the interface, the external interrupts can be either edge- or level-triggered.
Unlike the fixed interrupt-trap vector-table location of the ’320C30 and ’320C31 devices, the SMQ320C32 has
a user-relocatable interrupt-trap vector table. The interrupt-trap vector table must start on a 256-word boundary.
The interrupt and trap vector locations memory mapping is illustrated in Figure 10. The reset vector is fixed to
address 0h as shown in Figure 8.
