Data reading command is set.
Data reading starts.
Because the DOUT pin is an N-ch, open-drain output pin, be sure to connect an external pull-up resistor to this pin
(1 k to 10 k).
*: When data is read, a wait time tWAIT of 1 s is necessary since the rising of the eighth clock that has set the
command, until the falling of the first clock that has read the data.
