7. The 6–Bit Syndrome Word

This feature is available when the N22 pin is driven at a

high level.

7.1. No Errors

If there are no errors in the read Data or Check–Bit, all the

syndrome byte is ”00”. The EDAC flags are inactive.

No Error : SY=00

If there is an error in the Memory Check–bit (MC[..]),

only one bit of the syndrome is set to one.
