Hello, I am using development board ADSP21469 and development board for AD1938 TDM Daisy-Chain mode with 16-channel DAC. The two chips in question to work on for TDM AD1939 and AD1938. When the DSP, sending 16 channels the same, the system works, but when I send 16 different signals, the system mixes channels 0-8 1-9 2-10 3-11 4-12 5-13 6-14 7-15. I would understand if this anomaly depends on the configuration of the DSP or the configuration of the CODEC. Hello and Thanks
