7-0 Nothing is placed here. These should be fixed at “0”.
<<Notes>>
*1) Because the DCP buffer memory is used for both control read transfers and control write transfers, the CNTMD
bit will serve as the bit common to both, regardless of the transfer direction.
*2) This bit should be set to “0” in the peripheral mode.

<<Notes>>
*3) This bit should be set “00” in the peripheral mode.
*4) This should not be set to anything other than the USB specification. Also, because b2-b0 bits are fixed at “0”,
writing to these is invalid.
