The interpretation of line driver and normal mode DC load bit setting for AC load detection
is shown in
Table 6.
When bit IB1[D2] = 1, the AC load detection is enabled. The AC load detection can only
be performed after the amplifier has completed its start-up cycle and will not conflict with
the DC load detection.
The diagnostic information of the amplifier can be read via the I
are set on a failure and will be reset with the I
failure is removed, the microprocessor will know what was wrong by reading the I
The consequence of this procedure is that old information is read during the I
readout. Most actual information will be gathered after two successive read commands.
The DIAG pin will give actual diagnostic information (when selected). When a failure is
removed, the DIAG pin will be released instantly, independently of the I
