Legend: BOA = Base Offset Address for AIVT segment, which is the starting address of the last page of the

Boot Segment.

Legend:

BOA: Base Offset Address for AIVT, which is the starting address of the last page of the Boot Segment.

All addresses are in hexadecimal.

Note 1:

See Table 8-2 for the interrupt vector list.

AIVT is only available when a Boot Segment is implemented.
