USB-Interrupt Autovectors
The main USB interrupt is shared by 27 interrupt sources. The
FX1 provides a second level of interrupt vectoring, called
Autovectoring, to save code and processing time that is normally
required to identify the individual USB interrupt source. When a
USB interrupt is asserted, the FX1 pushes the program counter
on to its stack and then jumps to address 0x0043, where it
expects to find a “jump” instruction to the USB Interrupt service
routine.
The FX1 jump instruction is encoded as shown in
If Autovectoring is enabled (AV2EN = 1 in the INTSETUP
register), the FX1 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.
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.

interrupt sources.
