ADSP-21489 DMA for PDAP and memory data port

Question asked by marc_s1 on Nov 21, 2013

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 running.


However, for speed reasons I do not want to use the data output of the ADC in multiplexed mode anymore. I intend to connect the B output of the ADC to the external port memory data bus pins 0-14 of the ADSP-21489 and set up DMA to get the ADC data with the same clock I use for the DMA of the PDAP. Is this possible?


Thanks in advance for any help.
