23.8. Interrupts
The read-only USB0 interrupt flags are located in the USB registers shown in USB Register
Definition 23.11 through USB Register Definition 23.13. The associated interrupt enable bits are located in
the USB registers shown in USB Register Definition 23.14 through USB Register Definition 23.16. A USB0
interrupt is generated when any of the USB interrupt flags is set to 1. The USB0 interrupt is enabled via the
EIE1 SFR (see Section “17. Interrupts” on page 101).
Important Note: Reading a USB interrupt flag register resets all flags in that register to 0.
