USB OUT FIFO interrupt flag (UIF2)
The USB OUT FIFO Interrupt Flag register (see Table 116) contains flags that indicate
when an OUT Endpoint FIFO that was empty becomes full. Once set, firmware must
clear the flag by writing a '0' to the appropriate bit. When FIFOs are paired, only the
odd numbered FIFO Interrupt flags are active.
