Rewind
Specifies whether or not to rewind the buffer pointer.
0: The buffer pointer is not rewound.
1: The buffer pointer is rewound.
When the selected pipe is in the receiving direction,
setting this bit to 1 while the FIFO buffer is being read
allows re-reading the FIFO buffer from the first data
(in double buffer mode, re-reading the currently-read
FIFO buffer plane from the first data is allowed).

Do not set REW to 1 simultaneously with modifying
the CURPIPE bits. Before setting REW to 1, be sure
to check that FRDY is 1.
