I
If address byte bit R/W = 0, the TDA8589 expects 3 instruction bytes: IB1, IB2 and IB3; see Table 1 to Table 6.
After a power-on, all instruction bits are set to zero.
If address byte bit R/W = 1, the TDA8589 will send 4 data bytes to the microcontroller: DB1, DB2, DB3 and DB4; see
Table 7 to Table 10.
