READ OPERATION
When reading data back from the AD5301/AD5311/AD5321
DACs, the user must begin with an address byte after which
the DAC acknowledges that it is prepared to transmit data by
pulling SDA low. There are two different read operations. In the
case of the AD5301, the readback is a single byte that consists of
the eight data bits in the DAC register. However, in the case
of the AD5311 and AD5321, the readback consists of two bytes
that contain both the data and the power-down mode bits. The
read operations for the three DACs are shown in Figure 32 to
