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 KΩ to 10 KΩ ).

* : When data is read, a wait time tWAIT of 1μs 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.
