==Audio interface ==
''TBD: sostituire le sezioni con le informazioni sull'uso della periferica e del suo connettore''''Nell'esempio di seguito c'è la descrizione dell'interfaccia UART/console''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.
=== Description ===
The Audio interface SAI and SPDIF interfaces are available on the Evaluation Kit at the connector ''TBD:Jxxx''J8.
''Jxx'' J8 is a ''TBD:connector-type'' 20x2x2.54mm pin header expansion connector for the RS232 two-wires UART3 port, used for debug purposes (bootloader and operating system serial console)that delivers many interfaces unused on board.
===Signals ===
The following table describes the interface interfaces signals:
