Case 1:When Enable changes from FALSE to TRUE, Valid changes to TRUE. When Enable changes 
from TRUE to FALSE, Valid changes to FALSE. 
 
Case 2:When Enable changes from FALSE to TRUE, Valid changes to TRUE. When an error occurs in 
the instruction execution, Error changes to TRUE and ErrorID shows error codes and Valid keeps 
the state of TRUE. When Enable changes from TRUE to FALSE, Valid and Error both change to 
FALSE and the value in ErrorID changes to 0.
