There are two ways to use a single line to indicate that
all devices have their data ready, depending on
whether they are clocked synchronously. If all devices
have the same XIN clock and have been synchronized
using SYNC or reset commands, the DRDYOUT of any
device in the chain is used to represent all of them.
Alternatively, if the devices use a different XIN clock,
24-/16-Bit, 4-Channel, Simultaneous-Sampling,

connect DRDYIN of device 0 to ground, and connect
DRDYIN of device n to the DRDYOUT of device n-1 for
all devices. DRDYOUT does not go low until DRDIN is
low and the conversion of the device is complete. In this
configuration, DRDYOUT of the last device goes low only
when all devices in the chain have their data ready.
