Data Sheet
WRITING DATA
Data is written to the ADT7310 in eight bits or 16 bits, depending
on the addressed register. The first byte written to the device is
the command byte, with the read/write bit set to 0. The master
then supplies the 8-bit or 16-bit input data on the DIN line.
The ADT7310 clocks the data into the register addressed in
the command byte on the positive edge of SCLK. The master
finishes the write by pulling CS high.

Figure 18 shows a write to an 8-bit register, and Figure 19 shows
a write to a 16-bit register.
The master must begin a new write transaction on the bus for
every register write. Only one register is written to per bus
transaction.
