Audio interfaceEdit

There is no directly available Audio interface on the Evaluation Kit, two SAI and one SPDIF full duplex interfaces are available on the expansion connector.

DescriptionEdit

The SAI and SPDIF interfaces are available on the Evaluation Kit at the connector J8.

J8 is a 20x2x2.54mm pin header expansion connector that delivers many interfaces unused on board.
