Supplying a subaddress for each subaddress transaction is referred to as random I2C addressing. The
TAS5706A also supports sequential I2C addressing. For write transactions, if a subaddress is issued followed by
data for that subaddress and the 15 subaddresses that follow, a sequential I2C write transaction has taken place,
and the data for all 16 subaddresses is successfully received by the TAS5706A. For I2C sequential write
transactions, the subaddress then serves as the start address, and the amount of data subsequently transmitted,
before a stop or start is transmitted, determines how many subaddresses are written. As was true for random
addressing, sequential addressing requires that a complete set of data be transmitted. If only a partial set of data
is written to the last subaddress, the data for the last subaddress is discarded. However, all other data written is
accepted; only the incomplete data is discarded.
As shown in Figure 40, 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 will be a 0. After receiving the correct I2C device
address and the read/write bit, the DAP responds with an acknowledge bit. Next, the master transmits the
address byte or bytes corresponding to the TAS5706A internal memory address being accessed. After receiving
the address byte, the TAS5706A 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 TAS5706A
again responds with an acknowledge bit. Finally, the master device transmits a stop condition to complete the
single-byte data write transfer.
Figure 40. 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 DAP as shown in Figure 41. After receiving each data byte, the
TAS5706A responds with an acknowledge bit.
