AD7853/AD7853L
Interface Mode 1 Configuration
Figure 42 shows the flowchart for configuring the part in
Interface Mode 1. This mode of operation can only enabled by
writing to the control register and setting the 2/
3 MODE bit.
Reading and writing cannot take place simultaneously in this
mode as the DIN pin is used for both reading and writing.

Interface Modes 4 and 5 Configuration
Figure 43 shows the flowchart for configuring the AD7853/
AD7853L in Interface Modes 4 and 5, the self-clocking modes.
In this case it is not recommended to use the software conver-
sion start option. The read and write operations always occur
simultaneously and during conversion.
