Table 4-3: Violin Status Indications
Notes:
Without latch mode:
The status indications are reset when the fault disappears.
With latch mode:
The Short and Over Temperature Failure status indications are reset when the
enable signal is temporarily removed from the enable input.
Multiple faults:
Only the reading of the first fault is reliable. Additional faults add on to the
status outputs and the indication is therefore meaningless.
