Self-boot duration of an ADAU1401 / ADAU1701

The absolute maximum program + parameter + register data set would be about 10,000 bytes, including all overhead. If your sample rate is 48 kHz, the I2C clock frequency will be 384 kHz. So…

10,000 bytes x 8 bits = 80,000 total bits (i.e. 80,000 clock cycles).

80,000 clock cycles / 384,000 clock cycles per second = about 200 ms.

This is an approximation. In reality, the data size of the EEPROM will probably be significantly smaller, so the duration of the self-boot operation will be shorter.
