2.15 Communications Word Sequence
In the dual-word (telephone interface) mode, there are two data words that are presented to the DSP or
P
from the DR terminal. The first data word is the ADC conversion result occurring during the FSR time, and
the second is the serial data applied to DATA-DR during the FSD time. FSR is not asserted during secondary
communications and FSD is not asserted during primary communications.

DR Word Bit Pattern
The data word is the 14-bit conversion result of the receive channel to the processor in 2s complement
format. With 16-bit processors, the data is 16 bits long with the two LSBs at zero.
