8 / 64 page Interface description TDA7572 8/64 2 Interface description I2C bus and mode control pins are use to control operation. Default values of all the operating modes are deterministic, some of these values are intrinsic to the IC and some are determined by configurations pins. The configuration pins are read at power-up and copied into registers, which may later be modified using the I2C bus, if one is present. This allows varied operation in an environment where NOI2C bus is present, while allowing full control and override of pin programmed modes when used with I2C. Figure 1.
