Set DAC_FMx = 00,01,10
Set ADC_FMx = 00,01,10
Set ADC_CLK_SEL = 1
Set DIFx bits to proper serial format
Set ADC_OLx bits = 00,01
Set DAC_OLx bits = 00,01,10
Set DAC_SP M/S = 1
Set ADC_SP M/S = 0 or 1
Set EXT ADC SCLK = 0

This configuration will support up to 6 channels of DAC data and 6 channels of ADC data. OLM Config #3
will handle up to 20-bit ADC samples at an Fs of 48 kHz and 24-bit DAC samples at an Fs of 48 kHz. Since
the ADC’s data stream is configured to use the ADC_SDOUT output and the internal and external ADCs
are clocked from the ADC_SP, the sample rate for the DAC Serial Port can be different from the sample
rate of the ADC serial port.
