TDA7563
Examples of bytes sequence
1 - Turn-On diagnostic - Write operation
2 - Turn-On diagnostic - Read operation
The delay from 1 to 2 can be selected by software, starting from T.B.D. ms
3a - Turn-On of the power amplifier with 30dB gain, mute on, diagnostic defeat, CD = 2%.
3b - Turn-Off of the power amplifier
4 - Offset detection procedure enable
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).

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 leackage current or humidity between pins.
The delay from 4 to 5 can be selected by software, starting from T.B.D. ms
