When both of FIFO buffers are not empty.
When an IN token is received from the host to EP5
and both of FIFO buffers are empty.
At a reset
When 0 is written to by CPU
When IN token is issued from the host to EP4 and
the FIFO buffer is empty.
At a reset
When 0 is written to by CPU
When data is normally transferred from the function
to the host and an ACK handshake is returned after
the data to be transmitted to the host is written in
EP4.
At a reset
