If Autovectoring is enabled (AV2EN = 1 in the INTSET-UP
register), the FX2LP18 substitutes its INT2VEC byte. Therefore,
if the high byte (‘page’) of a jump-table address is preloaded at
location 0x0044, the automatically inserted INT2VEC byte at
0x0045 directs the jump to the correct address out of the 27
addresses within the page.
