Mode. In Chain Mode, SDO is always enabled and RDL/SDI
serves as the serial data input pin (SDI) where daisychain
data output from another ADC can be input.

This is useful for applications where hardware constraints
may limit the number of lines needed to interface to a large
number of converters. Figure 14 shows an example with
two daisy chained devices. The MSB of converter A will
appear at SDO of converter B after 16 SCK cycles. The
MSB of converter A is clocked in at the SDI/RDL pin of
converter B on the rising edge of the first SCK.
