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 directs

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, such as the USB Interrupt, can employ autovectoring. Table 4 on page 9 shows the

priority and INT4VEC values for the 14 FIFO/GPIF interrupt sources.
