7.13 Diagnostics
Diagnostic information can be read via the I
pin or on the STB pin. The DIAG pin has both fixed information (power-on reset occurred,
low battery and high battery) and, via the I
load fault and clip). This information will be seen at the DIAG pin as a logic OR. In case of
a failure, the DIAG pin remains LOW and the failure information can be read from the
microprocessor via the I
to minimize I
To have full control over the clipping information, the STB pin can be programmed as a
second clip detection pin. The clip detection level can be selected for all channels at once.
It is possible to select whether the clip information is available on the DIAG pin or on the
STB pin for each channel separately. It is, for instance, possible to distinguish between
clipping of the front and the rear channels.
Diagnostic information selection possibilities are shown in
Table 4.
