ERASE/WRITE DISABLE (EWDS):

To protect against accidental data disturb, the Erase/Write Disable (EWDS) instruction disables all programming

modes and should be executed after all programming operations. The operation of the Read instruction is independent

of both the EWEN and EWDS instructions and can be executed at any time.
