ADSP-21489 DMA for PDAP and memory data port
Hello, Currently I am using the ADSP-21479 with an AD9248 ADC connected (multiplexed output) to DAI pins 3 - 16. I have set up the PDAP with the PCG to clock in de ADC data via DMA. This is up and...

I also noticed, that TMDS input line of display has 3.3V. So, I understand why my signals have offset. Is it correct behaviour of TMDS input?
