Figure 16. Typical I2C Sequence
Use the I2C_ADDR pin (pin 2) to program the device for one of four addresses. These four addresses are
licensed I2C addresses and do not conflict with other licensed I2C audio devices. To communicate with the
TAS5414A and the TAS5424A, the I2C master uses addresses shown in Figure 16. Read and write data can be
transmitted using single-byte or multiple-byte data transfers.
Random Write
As shown in Figure 17, a single-byte data-write transfer begins with the master device transmitting a start
condition followed by the I2C device address and the read/write bit. The read/write bit determines the direction of
the data transfer. For a write data transfer, the read/write bit is a 0. After receiving the correct I2C device address
and the read/write bit, the TAS5414A or TAS5424A device responds with an acknowledge bit. Next, the master
transmits the address byte or bytes corresponding to the internal memory address being accessed. After
receiving the address byte, the TAS5414A or TAS5424A again responds with an acknowledge bit. Next, the
master device transmits the data byte to be written to the memory address being accessed. After receiving the
data byte, the TAS5414A or TAS5424A again responds with an acknowledge bit. Finally, the master device
transmits a stop condition to complete the single-byte data-write transfer.
Figure 17. Random Write Transfer
Sequential Write
A sequential data-write transfer is identical to a single-byte data-write transfer except that multiple data bytes are
transmitted by the master device to TAS5414A or TAS5424A as shown in Figure 17. After receiving each data
byte, the TAS5414A or TAS5424A responds with an acknowledge bit and the I2C subaddress is automatically
incremented by one.
