5.8 ECC

The 52 byte four way interleaved ECC processor provides user data verification and correction capability.
The first 4 bytes of ECC are check bytes for user data and the other 48 bytes are Read Solomon ECC. Each
interleave has 12 bytes for ECC. Hardware logic corrects up to 20 bytes (5 bytes for each interleave) errors
on-the-fly.

Following are some examples of error cases. An "O" means that the byte contains no error. An "X" means
that at least one bit of the byte is bad.

Table 12: Examples of error cases.
