17.5.4 USB ERROR INTERRUPT ENABLE
REGISTER (UEIE)
The USB Error Interrupt Enable register
(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.
