Failure Encoding in case of multiple faults
If multiple faults are stored in the failure register, the faults that are encoded in the DIAxx
bits can not be displayed simultaneously due to the encoding scheme that is used. In this
case, errors are encoded according to the following priority list.
– Priority 1: Under Voltage (please note that after removal of Under Voltage, the original
– Priority 2: Short circuit across the load
– Priority 3: all other short circuits
– Priority 4: open load
If a failure of higher priority is detected, the failures of lower priority are no longer visible
in the encoded SPI message.
Fault storage and reset of the Diagnosis Register DIA_REG
Register DIA_REG is reset upon the following conditions:
– With the rising edge of the CSN-Signal after the SPI-instruction RD_DIA. This reset
– When the voltage on DMS exceeds the threshold for detecting SPI-Mode (after Under
– A rising edge on EN while DIS=0 or a falling edge on DIS while EN=1 re-activates the
