Product List
There is a single interrupt generated from the USB module. Once vectored to the interrupt service routine (ISR) the firmware then parses the interrupt flags and determines the appropriate action. For example, if a transaction from a control transfer were received and the SIE determined that it was a valid packet then the USB0 module would set the USB0 interrupt flag. Once vectored to the interrupt the firmware would then read the interrupt flags register and see that it was endpoint 0 that generated the interrupt and jump to the routines that handle the control transfer.
