CONTROL REGISTER
The arrangement of the Control Register is shown below. The control register is a write only register and contains 14 bits of data.
The control register is selected by putting two 1s in ADDR1 and ADDR0. The function of the bits in the control register are de-
scribed below. The power-up status of all bits is 0.

A 0 in this bit position configures the input channels in pseudo differential mode. A 1 in this bit position
configures the input channels in single ended mode (see Table III).
These three bits are used to select the channel on which the conversion is performed. The channels can
be configured as eight single ended channels or four pseudo differential channels. The default selection
is AIN1 for the positive input and AIN2 for the negative input (see Table III for channel selection).
Power Management Bits. These two bits are used with the
SLEEP
pin for putting the part into various
Power-Down Modes (see Power-Down section for more details).
Theses two bits determine which register is addressed for the read operations (see Table II).

MODE
Interface Mode Select Bit. With this bit set to 0, Interface Mode 2 is enabled. With this bit set to 1,
Interface Mode 1 is enabled where DIN is used as an output as well as an input. This bit is set to 0 by
default after every read cycle; thus when using the Two-Wire Interface Mode, this bit needs to be set to
1 in every write cycle.
Conversion Start Bit. A logic one in this bit position starts a single conversion, and this bit is automati-
cally reset to 0 at the end of conversion. This bit may also used in conjunction with system calibration
(see Calibration section.)
Calibration Mode Bit. A 0 here selects self calibration, and a 1 selects a system calibration (see Table IV).
Calibration Selection Bits and Start Calibration Bit. These bits have two functions.
With the STCAL bit set to 1 the CALSLT1 and CALSLT0 bits determine the type of calibration per
formed by the part (see Table IV). The STCAL bit is automatically reset to 0 at the end of calibration.
With the STCAL bit set to 0 the CALSLT1 and CALSLT0 bits are decoded to address the calibration
register for read/write of calibration coefficients (see section on the Calibration Registers for more details).
