          AD7693
          Rev. A | Page 18 of 24
          CS MODE, 3-WIRE WITH BUSY INDICATOR
          This mode is usually used when a single AD7693 is connected
          to an SPI-compatible digital host having an interrupt input.
          The connection diagram is shown in Figure 36, and the
          corresponding timing is given in Figure 37.
          With SDI tied to VIO, a rising edge on CNV initiates a
          conversion, selects the CS mode, and forces SDO to high
          impedance. SDO is maintained in high impedance until the
          completion of the conversion irrespective of the state of CNV.
          Prior to the minimum conversion time, CNV can be used to
          select other SPI devices, such as analog multiplexers, but CNV
          must be returned low before the minimum conversion time
          elapses and then held low for the maximum possible conversion
          time to guarantee the generation of the busy signal indicator.
          When the conversion is complete, SDO goes from high
          impedance to low impedance. With a pull-up on the SDO line,
          this transition can be used as an interrupt signal to initiate the
          data reading controlled by the digital host. The AD7693 then
          enters the acquisition phase and powers down. The data bits are
          clocked out, MSB first, by subsequent SCK falling edges. The
          data is valid on both SCK edges. Although the rising edge can
          be used to capture the data, a digital host using the SCK falling
          edge will allow a faster reading rate, provided it has an
          acceptable hold time. After the optional 17th SCK falling edge or
          when CNV goes high (whichever occurs first), SDO returns to
          high impedance.
          If multiple AD7693s are selected at the same time, the SDO
          output pin handles this contention without damage or induced
          latch-up. Meanwhile, it is recommended to keep this contention
          as short as possible to limit extra power dissipation.
