CHANNEL ADDRESSING AND SPECIAL MODES
If the mode bits are not 00, then the data word D15 to D0
(AD5360) or D13 to D0 (AD5361) is written to the device.
Address Bit A4 to Address Bit A0 determine which channel or
channels is/are written to, while the mode bits determine to
which register (X1A, X1B, C, or M) the data is written, as
shown in Table 10 and Table 11. Data is to be written to the
X1A when the
A
/B bit in the control register is 0 or to the X1B
register when the bit is 1.
The AD5360/AD5361 have very flexible addressing that allows
writing of data to a single channel, all channels in a group, the
same channel in Group 0 and Group 1 or all channels in the
device. Table 13 shows all these address modes. It shows which
group(s) and which channel(s) is/are addressed for every
combination of Address Bit A4 to Address Bit A0.
