4.6.4 One Line Mode(OLM) Configurations
4.6.4a OLM Config #1
One Line Mode Configuration #1 can support up to 8 channels of DAC data, 6 channels of ADC data and
2 channels of S/PDIF received data. This is the only configuration which will support up to 24-bit samples
at a sampling frequency of 48 kHz on all channels for both the DAC and ADC.
Register / Bit Settings
Functional Mode Register (addr = 03h)
Set CODEC_FMx = SAI_FMx = 00,01,10
Set ADC_SP SELx = 00
Interface Format Register (addr = 04h)
Set DIFx bits to proper serial format
Set ADC_OLx bits = 00,01,10
Set DAC_OLx bits = 00,01,10
Misc. Control Register (addr = 05h)
Set CODEC_SP M/S = 1
Set SAI_SP M/S = 1
Set EXT ADC SCLK = 0
Description
CX_LRCK must equal SAI_LRCK; sample rate conversion not supported
Configure ADC data on CX_SDOUT, S/PDIF data on SAI_SDOUT
Select the digital interface format when not in one line mode
Select ADC operating mode, see table below for valid combinations
Select DAC operating mode, see table below for valid combinations
Configure CODEC Serial Port to master mode.
Configure Serial Audio Interface Port to master mode.
