When in diagnostic mode with mute enabled, if there
is excessive offset on any output, the MAX13325/
MAX13326 reports the condition through the I
face and the FLAG output. See Table 14.
When in diagnostic mode, if any of the output pairs is
excessively loaded, the MAX13325/MAX13326 issue a
warning and report the condition through the I
face and the FLAG output. The faulted channel is not
switched off. See Table 15.

When in diagnostic mode and the open-load detec-
tion is initiated, the selected channel is switched off for
1ms during which the diagnosis is taking place. Upon
detecting an open load on any channel, the MAX13325/
MAX13326 report the condition using the I
and the FLAG output. See Table 16.
When in diagnostic mode, if the MAX13325/MAX13326
