PRODUCTION DATA
The host should only use I2C_EC_SCL/SDA for loading a patch bundle. Once the boot process is complete, each port has a unique slave address on the I2C_EC_SCL/SDA bus as selected by the ADCINx pins. The slave address used by each port on the I2C2s bus are determined from the application configuration. The Port A slave address should be used for pushing the patch bundle since the Port B slave address is not available during the BOOT mode.
