FIFO Interrupt Enable registers
The FIFO Interrupt Enable registers contain the interrupt enable information for the
device block FIFOs. All interrupts are enabled by writing a 1 and are disabled by
writing a 0. The endpoint to register field mapping is identical to the FIFO Interrupt
Status registers.
