2 TAX5X1X Audio Serial Interface

TAX5X1X Converter supports 2 independent Audio Serial Interface (ASI); Primary ASI (PASI) and Secondary ASI (SASI). Primary ASI bus has direct mapping to the external pins and Secondary ASI bus is mapped or muxed through General Purpose Input Output pins. This is shown in the diagram below for TAX5212, TAX5112, TAX5211, TAX5111 device family and TAX5412, TAX5312, TAX5411, TAX5311 family.
