As shown in Figure 29, a single-byte data read transfer begins with the master device transmitting a start
condition followed by the I2C device address and the read/write bit. For the data read transfer, both a write
followed by a read are actually done. Initially, a write is done to transfer the address byte or bytes of the internal
memory address to be read. As a result, the read/write bit becomes a 0. After receiving the TAS5709 address
and the read/write bit, TAS5709 responds with an acknowledge bit. In addition, after sending the internal memory
address byte or bytes, the master device transmits another start condition followed by the TAS5709 address and
the read/write bit again. This time the read/write bit becomes a 1, indicating a read transfer. After receiving the
address and the read/write bit, the TAS5709 again responds with an acknowledge bit. Next, the TAS5709
transmits the data byte from the memory address being read. After receiving the data byte, the master device
transmits a not acknowledge followed by a stop condition to complete the single byte data read transfer.
Figure 29. Single-Byte Read Transfer
A multiple-byte data read transfer is identical to a single-byte data read transfer except that multiple data bytes
are transmitted by the TAS5709 to the master device as shown in Figure 30. Except for the last data byte, the
master device responds with an acknowledge bit after receiving each data byte.
