The FX2LP jump instruction is encoded as follows:
Table 3. INT2 USB Interrupts
If Autovectoring is enabled (AV2EN = 1 in the INTSET-UP register), the FX2LP substitutes its INT2VEC byte. Therefore, if the high
byte (“page”) of a jump table address is preloaded at the location 0x0044, the automatically inserted INT2VEC byte at 0x0045 directs
the jump to the correct address out of the 27 addresses within the page.
3.8.3 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.
and INT4VEC values for the 14 FIFO/GPIF interrupt sources.
