Error Syndrome Register

S6-S0

Bits SYNDROME6-0 reflect the syndrome value at the last
logging of an error. The seven-bit code indicates the
position of the data error. When all the bits are 0, there is
no error. Note that if the logged error was non-
correctable, then these bits are meaningless (refer to the

Syndrome Decoding

section).

Defaults Register 1

It is not recommended that non-test software write to this register.

RSIZ2-RSIZ0

that is assumed by the MCECC. They control the size as
follows:
