The TPS929121-Q1 automatically reloads all EEPROM code into the corresponding configuration registers every time after entering the fail-safe state. The TPS929121-Q1 implements a EEPROM CRC check after loading the EEPROM code to configuration register in fail-safe state. The calculated CRC result are sent to register CALC_EEPCRC and compared to the data in EEPROM register EEP_CRC, which stores the CRC code for all EEPROM registers. If the code in register CALC_EEPCRC is not matched to the code in register EEP_CRC, the TPS929121-Q1 turns off all channels output, pulls the ERR pin down with constant current sink to report the fault, and sets the registers including FLAG_EEPCRC and FLAG_ERR to 1. The CRC code for all the EEPROM registers must be burnt into EEPROM register EEP_CRC in the end of production line. The CRC code algorithm is described in EEPROM CRC Error in Normal State.
