ADV7619 APx port I2S Mapping

Question asked by snageli on Jul 19, 2015

So in the ADV7619 datasheet is shows the mapping as follows:

 

SPDIF0 SPDIF audio output

I2S0/SPDIF0 I2S audio (Channel 1, Channel 2)/SPDIF0

I2S1/SPDIF1 I2S audio (Channel 3, Channel 4)/SPDIF1

I2S2/SPDIF2 I2S audio (Channel 5, Channel 6)/SPDIF2

I2S3/SPDIF3 I2S audio (Channel 7, Channel 8)/SPDIF3

SCLK Bit clock

LRCLK Data output clock

 

Which result in the following:

 

AP1 - Front L/R

AP2 - Sub/Cen

AP3 - Rear L/R

AP4 - Surround Back L/R

 

I need to swap Sub and Center.  Is it possible to arrange channels within the specific I2Sx output?

 

I know there is

I2S_SPDIF_MAP_ROT[1:0] and I2S_SPDIF_MAP_INV but these only change where the I2S pairs go where I need to change that actual channel within the pair.

 

Thanks,

 

Shawn
