Random Read
As shown in Figure 19, 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 is a 0. After receiving the address and the read/write
bit, the TAS5414A or TAS5424A 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 TAS5414A or
TAS5424A address and the read/write bit again. This time the read/write bit is a 1, indicating a read transfer.
After receiving the address and the read/write bit, the TAS5414A or TAS5424A again responds with an
acknowledge bit. Next, the TAS5414A or TAS5424A 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.

Sequential Read
A sequential data-read transfer is identical to a single-byte data-read transfer except that multiple data bytes are
transmitted by the TAS5414A or TAS5424A to the master device as shown in Figure 20. Except for the last data
byte, the master device responds with an acknowledge bit after receiving each data byte and automatically
increments the I2C subaddress by one. Note: The fault registers do not have sequential read capabilities.
