PIC18F47J53 FAMILY
23.5.2 USB INTERRUPT ENABLE
REGISTER (UIE)
The USB Interrupt Enable (UIE) register
(Register 23-8) contains the enable bits for the USB
status interrupt sources. Setting any of these bits will
enable the respective interrupt source in the UIR
register.
The values in this register only affect the propagation
of an interrupt condition to the microcontroller’s inter-
rupt logic. The flag bits are still set by their interrupt
conditions, allowing them to be polled and serviced
without actually generating an interrupt.
