A master can read the TAS576xM register. The value of the register address is stored in a indirect index register in advance. The master sends a TAS576xM slave address with a read bit after storing the register address. Then the TAS576xM transferes the data which the index points to. When auto-increment is enabled, the index register is incremented by 1 automatically. When the index register reaches 0x7F, the next value is 0x0. The following table shows the read operation.
|Data Type||St||Slave addr||W||ACK||inc||reg addr||ACK||Sr||Slave addr||R||ACK||data||ACK||NACK||Sp|
|M = Master Device; S = Slave Device; St = Start Condition; Sr = Repeated start condition; Sp = Stop Condition; W = Write; R 0 read;
NACK = Acknowledge
