4.1 Changing the Default I2C Address of the PCM6xx0 EVM
When multiple PCM6xx0 EVMs are connected to a single I2C bus, each EVM must have a unique I2C address. The I2C address is set by pullups and pulldowns on the Control and GPIO Selection at the underside of the board, as shown in Figure 20. Placement of the resistors in this section, as shown in Table 1, controls the I2C address of each PCM6xx0 device.
