Has the data flash correctly erased according to the procedure?

Latest Updated:06/20/2013

Question:

Although the data flash was correctly erased according to the procedure, when I read a value from the erased area a value other than FFh is read. Has the data flash been correctly erased?

Answer:

After a data flash area has been erased, the value cannot be read correctly. If read, the value is undefined. Please use the blank check command to check whether the data flash has been correctly erased (blanked).
