If the selected endpoint is set to OUT, this becomes to receive data
FIFO register.
If the selected endpoint is set to IN, this becomes to transmit data
FIFO register.
If the selected endpoint is set to 8-bit mode, lower 8 bit [7:0] are valid.
Read operation when the endpoint appointed direction IN, or
write operation when the endpoint appointed direction OUT, is inhibited.
