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
