E_ABNRM[11:0]
These EEPROM contain the configuration data for self-diagnostic functions. To inactivate a specific
diagnostic function, the corresponding bit should be set to “1”. To validate the user configuration in
Normal Mode, store the configuration data to E_ABNRM via WriteEEPROM operation code in User
Mode.
