(Block erase, Programming)
Execute the clear status register command (50
16
) to clear the status register.
Confirm whether the command has correctly been input or not; and then,
start the operation again.
Perform the block erase operation again.
If an error occurs even after the above operation is performed, the block cannot be used.
Perform the programming operation again.
If an error occurs even after the above operation is performed, the word cannot be used.
Note:
Under the condition that any of SR.5 and SR.4 = 1 , none of the programming,
block erase, and erase all block commands can be accepted. Before execution
of these commands, execute the clear status register command (50
16
) in advance.
