4.7 Handling of the diagnostics information

As various kinds of information are available at the same pin (clipping detection, output fault,

thermal proximity), this signal must be handled properly in order to discriminate each event.

This could be done by taking into account the different timing of the diagnostic output during

each case.

Normally the clip detector signalling produces a low level at pin 10 that is shorter referred to

every kind of fault detection; based on this assumption an interface circuitry to differentiate

the information is represented in the following schematic.
