Serial Data Input (Input) -
Two’s complement MSB-first serial data is input on this pin. The
required relationship between the left/right clock, serial clock and serial data is defined by the
DIF1-0 pins. The options are detailed in Figures 8 - 11.
DIF0, DIF1

Digital Interface Format (Input) -
The required relationship between the left/right clock, serial
clock and serial data is defined by the Digital Interface Format. The options are detailed in Fig-
ures 8 - 11.
DEM0, DEM1
