If Autovectoring is enabled (AV2EN = 1 in the INTSET-UP
register), the NX2LP-Flex substitutes its INT2VEC byte.
Therefore, if the high byte (‘page’) of a jump-table address is
preloaded at location 0x544, the automatically-inserted
INT2VEC byte at 0x545 will direct the jump to the correct
address out of the 27 addresses within the page.
FIFO/GPIF Interrupt (INT4)
Just as the USB Interrupt is shared among 27 individual
USB-interrupt sources, the FIFO/GPIF interrupt is shared
among 14 individual FIFO/GPIF sources. The FIFO/GPIF
Interrupt, like the USB Interrupt, can employ autovectoring.
Table 4 shows the priority and INT4VEC values for the 14
FIFO/GPIF interrupt sources.
