+* (one space for transfer complete status information also pushed to the
+* FIFO with each endpoint's last packet)
+*
+* (ii)MINIMUM RAM space required for each IN EP Tx FIFO = MAX packet size for
+* that particular IN EP. More space allocated in the IN EP Tx FIFO results
+* 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.
