Digital Interface Formats
The serial port operates as a slave and supports the I²S, Left-Justified, Right-Justified, One-Line Mode
(OLM) and TDM digital interface formats with varying bit depths from 16 to 32 as shown in
Data is clocked into the DAC on the rising edge. OLM and TDM configurations are only supported in Soft-
ware Mode.
