FUNCTIONAL DESCRIPTION
I2C-bus interface
The I2C-bus interface is a receive-only slave, which accepts data according the format shown in Table 1.
Table 1
I2C-bus format (see note 1)
Note
1. S = START condition; A2 to A0 = programmable address bits; A = Acknowledge; I3 to I0 = Instruction bits;
SD to SA = subaddress bits; X = don’t care; D5 to D0 = data bits; P = STOP condition.
Valid addresses are:
TDA8444 and TDA8444AT: 40H, 42H, 44H, 46H, 48H, 4AH, 4CH and 4EH
TDA8444T: 48H, 4AH, 4CH and 4EH (A2 is always logic 1).
All other addresses cannot be acknowledged by the circuit. The actual slave address depends on the programmable
address bits A2, A1 and A0. This way up to eight circuits can be used on one I2C-bus.
Valid instructions are: 00H to 0FH; F0H to FFH.
