A data read command is set.
Data is read.
Transmission (data read)
Note : When data is read, a wait time tWAIT of 1 µs 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.
Remark : Because the DOUT pin is an N-ch, open-drain output pin, be sure to connect an external pull-up resistor (1 kΩ to 10 kΩ) to this
pin.
