WRITING TO THE AD7991/AD7995/AD7999
By default, each part operates in read-only mode and all four chan-
nels are selected as enabled in the configuration register. To write
to the AD7991/AD7995/AD7999 configuration register, the user
must first address the device.

The configuration register is an 8-bit register; therefore, only
one byte of data can be written to this register. However, writing
a single byte of data to this register consists of writing the serial
bus write address, followed by the data byte written (see Figure 24).
