VALINFO

L2 capture registers valid

0 L2 capture registers contain no valid information or no enabled errors were detected.

1 L2 capture registers contain information of the first detected error which has reporting

enabled. Software must clear this bit to unfreeze error capture so error detection hardware

can overwrite the capture address/data/attributes for a newly detected error.
