1: The high bandwidth isochronous is supported.
0: The high bandwidth isochronous is not supported.
1: The UTMI data bus is a 16-bit data path at 30MHz.
0: The UTMI data bus is a 8-bit data path at 60MHz.
1: The DPRAM is natively byte-write capable.
0: The DPRAM byte write lanes have shadow logic implemented in the USBB IP interface.
This field indicates the maximal FIFO size, i.e., the DPRAM size:
