Data reading command is set.
Data reading starts.
Because the D
OUT
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 t
WAIT
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.
