Serial Ports support for ADAU1467 & ADAU1462

Ks929 on Oct 21, 2019

As per the ''Selection table for SigmaDSP audio processors' Serial I/O Ports supported for ADAU1467 & ADAU1462 is mentioned as 12 ports for input and output.

But while referring Data sheet, serial ports supported is 4 only. Please clarify the same.

Kalaiselvi,

The table is not quite correct. The ADAU1463/67 have four full serial input ports and four full serial output ports each with their own BCLK and LRCLK lines. In addition, there are eight serial data lines that may be used either as input or output pins. Each of these eight lines must be assigned to, and used at the same rate as, one of the four input or four output serial ports. If they are not used as serial data lines, they may be used as GPIO. I hope that is clearer.
