OE must be high only when WE and CE are both low. 3. The data can be 40H or 10H. 4. For chip erase, any address can be used. For plane erase or sector erase, the address depends on what plane or sector is to be erased. 5. For chip erase, the data should be 21H, for plane erase, the data should be 22H, and for sector erase, the data should be 20H. 34.
