PCM AND ADPCM INPUT/OUTPUT
Since the organization of the input and output time slots on the DS2164Q does not depend on the
algorithm selected, it always assumes that PCM input and output will be in 8-bit bytes and that ADPCM
input and output will be in 4-bit bytes. Figure 12 demonstrates how the DS2164Q handles the I/O for the
three different algorithms. In the figure, it is assumed that channel X is in the compression mode
(CP/ EX = 1) and channel Y is in the expansion mode (CP/ EX = 0). Also, it is assumed that both the input
and output time slots for both channels are set to 0.

NOTE:
1. The bit after the LSB in the 24 kbps ADPCM output will only be a 1 when the DS2164Q is operated
in the software mode and is programmed to perform 24 kbps compression; in all other configurations,
it will be a 0.
