7.3.10.2.1.2 I2C Address Setting

The I2C controller must only use I2Ct_SCL/SDA for loading a patch bundle.

Once the boot process is complete, the port has a unique target address on the I2Ct_SCL/SDA bus as selected by the ADCINx pins.
Table 7-5 I2C Default Target Address for I2Ct_SCL/SDA.
I2C ADDRESS INDEX (DECODED FROM ADCIN1 AND ADCIN2)(1)TARGET ADDRESSAVAILABLE DURING BOOT
BIT 7BIT 6BIT 5BIT 4BIT 3BIT 2BIT 1BIT 0
