7.4.3 Syndrome Table: Decode to Bit in Error
The syndrome is an 8-bit value that decodes to the bit in error. The bit in error can be a bit among the 64
data bits or a bit among the 8 ECC check bits. A syndrome value of 0000 0000 indicates there is no error.
Any other syndrome combinations not shown in the table are uncorrectable multi-bit error. Errors of three
of more bits may escape detection. The syndrome decoding is shown in Table 7-2.
