12.34 DIGITAL AUDIO DATA FORMATS
I
used when the ADC is enabled, unless the FORCE_RQ bit is set. If the PCM receiver interface is operated in slave mode the clock
and sync should be enabled at the same time because the PCM receiver uses the first PCM frame to calculate the PCM interface
format. This format can not be changed unless a soft reset is issued. Operating the LM49370 in master mode eliminates the risk
of sample rate mismatch between the data converters and the audio interfaces.
In slave mode, the PCM and I
formats are as followed:

S master mode can only be used when the DAC is enabled unless the FORCE_RQ bit is set. PCM Master mode can only be

S receivers only record the 1st 16 and 18 bits of the serial words respectively. The I
