USB ERROR INTERRUPT ENABLE

The

USB

Error

Interrupt

Enable

(Register 17-10) contains the enable bits for each of

the USB error interrupt sources. Setting any of these

bits will enable the respective error interrupt source in

the UEIR register to propagate into the UERR bit at

the top level of the interrupt logic.

As with the UIE register, the enable bits only affect the

propagation of an interrupt condition to the micro-

controller’s interrupt logic. The flag bits are still set by

their interrupt conditions, allowing them to be polled

and serviced without actually generating an interrupt.
