and shows how they are enabled.
Figure 18-12. Interrupts and events scheme summary.
The transaction complete interrupt is generated per endpoint. When an interrupt occurs, the
associated endpoint number is registered and optionally added to the FIFO. The following two
interrupt sources use the interrupt vector:
