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 16th rising SCLK

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 16th SCLK edge, the control register

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.
