       Select. This bit selects whether the next operation is a read or write operation to the selected register.
      A “0” indicates a write cycle for the next operation to the appropriate register, while a “1” indicates a read opera-
      tion from the appropriate register.
      Standby. Writing a “1” to this bit puts the part into its standby or power-down mode. In this mode, the part con-
      sumes only 8 
      μ
      A of power supply current. The part retains its calibration coefficients and control word information
      when in STANDBY. Writing a “0” to this bit places the part in its normal operating mode. The serial interface on
      the AD7707 remains operational when the part is in STBY mode.
      Channel Select. These two bits select a channel for conversion or for access to the calibration coefficients as out-
      lined in Table X. Three pairs of calibration registers on the part are used to store the calibration coefficients fol-
      lowing a calibration on a channel. They are shown in Tables VII for the AD7707 to indicate which channel
      combinations have independent calibration coefficients. With CH1 at Logic 1 and CH0 at a Logic 0, the part looks
      at the LOCOM input internally shorted to itself. This can be used as a test method to evaluate the noise perfor-
      mance of the part with no external noise sources. In this mode, the LOCOM input should be connected to an
      external voltage within the allowable common-mode range for the part.
