(3) BSWP (Byte Swap Mode) Bit (b7)
(4) ISEL (Buffer Select) Bit (b0)
This bit sets the endian of the EP0_FIFO Data Register.
When this bit is set to “0”, the EP0_FIFO Data Register gets such as little endian.
When this bit is set to “1”, the EP0_FIFO Data Register gets such as big endian.
This bit selects the buffer transfer direction of the endpoint 0 used in the control transfer.
When “0” is written to this bit, the buffer for control write transfer is valid.
When “1” is written to this bit, the buffer for control read transfer is valid.
