7.4.9.2 Control Interface

The TAS2505A-Q1 control interface supports SPI or I2C communication protocols, with the protocol selectable using the SPI_SEL pin. For SPI, SPI_SEL should be tied high; for I2C, SPI_SEL should be tied low. TI does not recommend changing the state of SPI_SEL during device operation.
