11.3. Output Data Hardware Configuration
The naming convention for the DAO configuration
is as follows:
where the parameters are defined as:
A - DAO Mode (Master/Slave for LRCLK and
SCLK)
B - Data Format
C - MCLK Frequency
D - SCLK Frequency
E - SCLK Polarity
The following tables show the different values for
each parameter as well as the hex message that
needs to be sent. When creating the hardware
configuration message, only one hex message
should be sent per parameter.
