Figure 38. Single-Byte Write Transfer
A multiple-byte data write transfer is identical to a single-byte data write transfer except that multiple data bytes
are transmitted by the master device to the TPA6130A2 as shown in Figure 39. After receiving each data byte,
the TPA6130A2 responds with an acknowledge bit.
Figure 39. Multiple-Byte Write Transfer
As shown in Figure 40, 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 of the internal memory
address to be read. As a result, the read/write bit is set to a 0.
After receiving the TPA6130A2 address and the read/write bit, the TPA6130A2 responds with an acknowledge
bit. The master then sends the internal memory address byte, after which the TPA6130A2 issues an
acknowledge bit. The master device transmits another start condition followed by the TPA6130A2 address and
the read/write bit again. This time the read/write bit is set to 1, indicating a read transfer. Next, the TPA6130A2
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 40. 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 TPA6130A2 to the master device as shown in Figure 41. With the exception of the last
data byte, the master device responds with an acknowledge bit after receiving each data byte.
