/*******************************************************************************
*                     FIFO Size Configuration in Host mode
*  
*  (i) Receive data FIFO size = (Largest Packet Size / 4) + 1 or 
*                             2x (Largest Packet Size / 4) + 1,  If a 
*                             high-bandwidth channel or multiple isochronous 
*                             channels are enabled
*
*  (ii) For the host nonperiodic Transmit FIFO is the largest maximum packet size 
*      for all supported nonperiodic OUT channels. Typically, a space 
*      corresponding to two Largest Packet Size is recommended.
*
*  (iii) The minimum amount of RAM required for Host periodic Transmit FIFO is 
*        the largest maximum packet size for all supported periodic OUT channels.
*        If there is at least one High Bandwidth Isochronous OUT endpoint, 
*        then the space must be at least two times the maximum packet size for 
*        that channel.
