4.6.4.5

OLM Config #5

This One-Line Mode configuration can support up to 6 channels of DAC data 2 channels of ADC data and

2 channels of S/PDIF received data and will handle up to 24-bit samples at a sampling frequency of 48 kHz

on all channels for both the DAC and ADC. The output data stream of the internal ADCs can be configured

to use the CX_SDOUT output and run at the CODEC_SP clock speeds or to use the SAI_SDOUT data

output and run at the SAI_SP rate. The CODEC_SP and SAI_SP can operate at different Fs rates.

Description

Functional Mode Register (addr = 03h)

Set CODEC_FMx = 00,01,10

CX_LRCK can run at SSM, DSM, or QSM independent of SAI_LRCK

Set SAI_FMx = 00,01,10

SAI_LRCK can run at SSM, DSM, or QSM independent of CX_LRCK

Set ADC_SP SELx = 00,01,10

Configure ADC data to use CX_SDOUT and CODEC_SP clocks, or

SAI_SDOUT and SAI_SP cocks.

Interface Format Register (addr = 04h)

Set DIFx bits to proper serial format

Select the digital interface format when not in one line mode

Set ADC_OLx bits = 00

Set ADC operating mode to Not One Line Mode since only 2 channels of

ADC are supported

Set DAC_OLx bits = 00,01

Select DAC operating mode, see table below for valid combinations

Misc. Control Register (addr = 05h)

Set CODEC_SP M/S = 0 or 1

Set CODEC Serial Port to master mode or slave mode.

Set SAI_SP M/S = 0 or 1

Set Serial Audio Interface Port to master mode or slave mode.

Set EXT ADC SCLK = 0

External ADCs are not used. Leave bit in default state.
