<<Notes>>
*6) The valid value for the BUFSIZE bit depends on the selected PIPE by the PIPESEL bit of the PIPESEL register.
When using PIPE1-5, this bit can select “BUFSIZE=00-1F”
When using PIPE6-7, writing to this bit is invalid.
*7) The BUFNMB bit can be set to match the user system when PIPE1-5 are selected.
"BUFNMB=0-3"is used exclusively for the DCP."BUFNMB=4-5"is allocated to PIPE6-7.
When using PIPE6, writing to this bit is invalid, and "BUFNMB=4” is always used for reading.
When using PIPE7, writing to this bit is invalid, and “BUFNMB=5” is always used for reading.

*8) This bit should be set “00” in the peripheral mode.
*9) The MXPS bit should be set to"0x00”, or the setting defined by the USB specification should be used.
*10) The default value of MXPS bit is "0x0" when "PIPSEL=0", and "0x40" when select "PIPESEL>0".
