NOTE:
1. The table indicates the decoding of the seven syndrome bits to identify
the bit-in-error for a single-bit error, or whether a double or triple-bit
error was detected. The all-zero case indicattes no error detected.
* = No errors detected
# = The number of the single bit-in-error
T = Two errors detected
M = three or more errors detected
