* in a better performance on the USB and can hide latencies on the AHB.
*
* (iii) TXn min size = 16 words. (n : Transmit FIFO index)
* (iv) When a TxFIFO is not used, the Configuration should be as follows:
* case 1 : n > m and Txn is not used (n,m : Transmit FIFO indexes)
* --> Txm can use the space allocated for Txn.
* case2 : n < m and Txn is not used (n,m : Transmit FIFO indexes)
* --> Txn should be configured with the minimum space of 16 words
* (v) The FIFO is used optimally when used TxFIFOs are allocated in the top
* of the FIFO.Ex: use EP1 and EP2 as IN instead of EP1 and EP3 as IN ones.
