7.3.2

Priority of diagnosis bit setting

The diagnosis bits OxDIA in register DIAG1 are set according to the diagnosis information .

In OFF-state, open load and short to GND diagnosis information are available. In ON-State, overcurrent

protection and short to battery diagnosis information are available.

To avoid conflicts, the setting of the diagnosis bits is performed according to the priorites below:

short to battery (highest priority)

open load

short to GND (lowest priority)

In case of a parallel diagnostic condition, the bit with higher priority is set. The information on the occurrence

of a diagnosis condition with lower priority is lost.

The diagnosis bits are set to the actual diagnosis status of the device by a read command via SPI.
