A master can write to any TAS576xM registers using single or multiple accesses. The master sends a TAS576xM slave address with a write bit, a register address with auto-increment bit, and the data. If auto-increment is enabled, the address is that of the starting register, followed by the data to be transferred. When the data is received properly, the index register is incremented by 1 automatically. When the index register reaches 0x7F, the next value is 0x0. The following table shows the write operation.
|Data Type||St||Slave addr||W||ACK||inc||reg addr||ACK||Write data1||ACK||Write data2||ACK||ACK||Sp|
|M = Master Device; S = Slave Device; St = Start Condition; Sp = Stop Condition; W = Write; ACK = Acknowledge|
