Result of the selftest coded as an integer value with each bit representing the result of a different sub part test. Bits set in the result indicate error conditions of the sub part tests. Meaning of the bits: Bit 0: communication error with card 1 Bit 1: communication error with card 2 Bit 2: communication error with card 3 Bit 3: communication error with card 4 Bit 4: communication error with card 5 Bit 24: main and redundant eeprom 2 are different Bit 25: main and redundant eeprom 1 are different Bit 27: error on redundant eeprom 2 Bit 28: error on redundant eeprom 1 Bit 29: error on main eeprom 2 Bit 30: error on main eeprom 1
