Processor Description (V40)
The vector of an interrupt source must be known before the location
of the service routine address can be determined. The interrupt vector
table, shown in Table 5-5, lists the vectors for the sources of
interrupts. As an example, assume you need to write a service routine
to handle a non-maskable interrupt (NMI) request. The vector for
NMI is two, as seen in the Table 5-5. The address of the NMI service
routine is determined by the application, but that address must be
programmed in the vector table at 8h.
