A correct turn on/off sequence respectful of the diagnostic timings and producing no audible noises could be as
follows (after battery connection):
TURN-ON: PIN2 > 7V --- 10ms --- (STAND-BY OUT + DIAG ENABLE) --- 500 ms (min) --- MUTING OUT
TURN-OFF: MUTING IN --- 20 ms --- (DIAG DISABLE + STAND-BY IN) --- 10ms --- PIN2 = 0
Car Radio Installation: PIN2 > 7V --- 10ms DIAG ENABLE (write) --- 200 ms --- I

C read (repeat until All faults
disappear).
OFFSET TEST: Device in Play (no signal) -- OFFSET ENABLE - 30ms - I

Data transmission from microprocessor to the TDA7563PD and viceversa takes place through the 2 wires

C BUS interface, consisting of the two lines SDA and SCL (pull-up resistors to positive supply voltage
must be connected).

C BUS INTERFACE
9.1 Data Validity
As shown by fig. 28, the data on the SDA line must be stable during the high period of the clock. The HIGH and
LOW state of the data line can only change when the clock signal on the SCL line is LOW.
9.2 Start and Stop Conditions
As shown by fig. 29 a start condition is a HIGH to LOW transition of the SDA line while SCL is HIGH. The stop
condition is a LOW to HIGH transition of the SDA line while SCL is HIGH.
9.3 Byte Format
Every byte transferred to the SDA line must contain 8 bits. Each byte must be followed by an acknowledge bit.
The MSB is transferred first.
