USB ERROR INTERRUPT ENABLE
REGISTER (UEIE)
The USB Error Interrupt Enable register (Register 14-10)
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
microcontroller’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.
