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 mute on, diagnostic defeat.
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

DIAGNOSTICS FUNCTIONAL DESCRIPTION:
a) TURN-ON DIAGNOSTIC.
It is activated at the turn-on (stand-by out) under I
To verify if any of the above misconnections are in place, a subsonic (inaudible) current pulse (fig. A) is internally
generated, sent through the speaker(s) and sunk back.The Turn On diagnostic status is internally stored until a
successive diagnostic pulse is requested (after a I2C reading).
If the "stand-by out" and "diag. enable" commands are both given through a single programming step, the pulse
takes place first (power stage still in stand-by mode, low, outputs= high impedance).

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
– SHORT TO GND
– SHORT TO Vs
– SHORT ACROSS THE SPEAKER
