Examples of bytes sequence

TDA7563B

1 - Turn-On diagnostic - write operation

Start Address byte with D0 = 0 ACK IB1 with D6 = 1 ACK IB2 ACK STOP

2 - Turn-On diagnostic - read operation

Start Address byte with D0 = 1 ACK DB1 ACK DB2 ACK DB3 ACK DB4 ACK STOP

The delay from 1 to 2 can be selected by software, starting from 1ms

3a - Turn-on of the power amplifier with 30dB gain, mute on, diagnostic defeat, CD = 2%

5 - Offset detection procedure stop and reading operation (the results are valid only for the

offset detection bits (D2 of the bytes DB1, DB2, DB3, DB4)

.

Start Address byte with D0 = 1 ACK DB1 ACK DB2 ACK DB3 ACK DB4 ACK STOP

● The purpose of this test is to check if a D.C. offset (2V typ.) is present on the outputs,

produced by input capacitor with anomalous leakage current or humidity between pins.

● The delay from 4 to 5 can be selected by software, starting from 1ms
