CHANNEL ADDRESSING AND SPECIAL MODES
If the mode bits are not 00, the data-word D15 to D0 (AD5372)
or D13 to D0 (AD5373) is written to the device. Address Bit A5
to Address Bit A0 determine which channels are written to, and
the mode bits determine to which register (X1A, X1B, C, or M)
the data is written, as shown in Table
be written to the X1A register when the A/B bit in the control
register is 0, or to the X1B register when the A/B bit is 1.
The AD5372/AD5373 have very flexible addressing that allows
the writing of data to a single channel, all channels in a group,
the same channel in Group 0 to Group 3, the same channel in
Group 1 to Group 3, or all channels in the device. Table 14 shows
which groups and which channels are addressed for every
combination of Address Bit A5 to Address Bit A0.
