SLASEM6B October 2017 – October 2018 TAS2770
The serial control interface supports both single-byte and multiple-byte read/write operations for all registers. During multiple-byte read operations, the TAS2770 responds with data, a byte at a time, starting at the register assigned, as long as the master device continues to respond with acknowledges.
The TAS2770 supports sequential I2C addressing. For write transactions, if a register is issued followed by data for that register and all the remaining registers that follow, a sequential I2C write transaction has taken place. For I2C sequential write transactions, the register issued then serves as the starting point, and the amount of data subsequently transmitted, before a stop or start is transmitted, determines to how many registers are written.
