Write Operation
Figure 14 also shows the timing diagram for a serial write to the
ADT7302. The write operation takes place at the same time as
the read operation. Only the third bit in the data stream provides
a user-controlled function. This third bit is the power-down bit,
which, when set to 1, puts the ADT7302 into shutdown mode.
In addition to the power-down bit, all bits in the input data
stream should be 0 to ensure correct operation of the ADT7302.

Data is loaded into the control register on the 16
edge; the data takes effect at this time. Therefore, if the part is
programmed to go into shutdown, it does so at this point. If CS
is brought high before this 16
is not loaded and the power-down status of the part does not
change. Data is clocked into the ADT7302 on the rising edge of
SCLK.
