  81 *                   OUT endpoint control information +
  82 *                   data OUT packets + miscellaneous
  83 *      Space = ONE 32-bits words
  84 *     --> RAM for setup packets = 10 spaces
  85 *        (n is the nbr of CTRL EPs the device core supports)
  86 *     --> OUT EP CTRL info      = 1 space
  87 *        (one space for status information written to the FIFO along with each
  88 *        received packet)
  89 *     --> data OUT packets      = (Largest Packet Size / 4) + 1 spaces
  90 *        (MINIMUM to receive packets)
  91 *     --> OR data OUT packets  = at least 2*(Largest Packet Size / 4) + 1 spaces
  92 *        (if high-bandwidth EP is enabled or multiple isochronous EPs)
  93 *     --> miscellaneous = 1 space per OUT EP
  94 *        (one space for transfer complete status information also pushed to the
  95 *        FIFO with each endpoint's last packet)
  96 *
  97 *  (ii)MINIMUM RAM space required for each IN EP Tx FIFO = MAX packet size for
  98 *       that particular IN EP. More space allocated in the IN EP Tx FIFO results
  99 *       in a better performance on the USB and can hide latencies on the AHB.
 100 *
 101 *  (iii) TXn min size = 16 words. (n  : Transmit FIFO index)
 102 *   (iv) When a TxFIFO is not used, the Configuration should be as follows:
 103 *       case 1 :  n > m    and Txn is not used    (n,m  : Transmit FIFO indexes)
 104 *       --> Txm can use the space allocated for Txn.
 105 *       case2  :  n < m    and Txn is not used    (n,m  : Transmit FIFO indexes)
 106 *       --> Txn should be configured with the minimum space of 16 words
 107 *  (v) The FIFO is used optimally when used TxFIFOs are allocated in the top
 108 *       of the FIFO.Ex: use EP1 and EP2 as IN instead of EP1 and EP3 as IN ones.
