A data read command is set.

Data is read.

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).

Note 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.
