4.8.2
The main USB interrupt is shared by 27 interrupt sources. To
save the code and processing time that normally would be
required to identify the individual USB interrupt source, the
FX1 provides a second level of interrupt vectoring, called
Autovectoring. When a USB interrupt is asserted, the FX1
pushes the program counter onto its stack 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
Table 4-3
.
If Autovectoring is enabled (AV2EN = 1 in the INTSETUP
register), the FX1 substitutes its INT2VEC byte. Therefore, if
USB-Interrupt Autovectors
the high byte (“page”) of a jump-table address is preloaded at
location 0x0044, the automatically-inserted INT2VEC byte at
0x0045 will direct the jump to the correct address out of the 27
addresses within the page.
4.8.3
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 4-4
shows
the priority and INT4VEC values for the 14 FIFO/GPIF
interrupt sources.
