I am applying 12.288 MHZ to MCLKIN on powerup. The ADAU1372 starts outputting a start condition followed by 0xA0 on the I2C bus. This happens to be the base address for a 24 series serial EPROM. The ADAU1372 will stop when I create a bus collision but then will not ack when I send its address. Have I stumbled into a standalone mode for the ADAU1372, and if so, how do I prevent it.
