16.8. Interrupts
The read-only USB0 interrupt flags are located in the USB registers shown in USB Register
Definition 16.11 through USB Register Definition 16.13. The associated interrupt enable bits are located in
the USB registers shown in USB Register Definition 16.14 through USB Register Definition 16.16. 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
Important Note: Reading a USB interrupt flag register resets all flags in that register to ‘0’.
