3.4 I2C Target Address Selection

TAS2320 supports 4 different I2C selectable addresses. When SEL1 is set to I2C Mode by shorting the middle row to the top pin (J86), the device checks the state of SEL4 to select the device address. Use SEL4 jumper to select the required I2C address.

CAUTION: By default, the amplifier is configured to play the audio slot according to the I2C address, that is, in a TDM system, device with address 0x90 plays slot 0, address 0x92 plays slot 1, and so forth.
