Abstract
A method and apparatus can include: audio interface pins coupled to swappable connections including a BCLK, an LRCLK, a DIN, and a DOUT; a BCLK determiner configured to identify the BCLK as the swappable connection with a highest frequency; an LRCLK determiner configured to: measure cycle lengths, compare the cycle lengths to a pre-defined multiple, identify the LRCLK as the swappable connections, and output an association between the LRCLK and one of the audio interface pins; and a mode determiner configured to identify and output a mode based on the association of the BCLK to the audio interface pins and the association of the LRCLK to the audio interface pins.
