CAUTION  
Field margin levels must only be used during verify of the initial factory  
programming.  
NOTE  
Field margin levels can be used to check that Flash memory contents have  
adequate margin for data retention at the normal level setting. If unexpected  
results are encountered when checking Flash memory contents at field  
margin levels, the Flash memory contents should be erased and  
reprogrammed.
