1. Bus operations are defined in 3.1 Bus operation.
2. First bus cycle command address should be the same as the second cycle address.
3. ID=Data read from identifier codes. (See 5.2, 5.3 ).
4. Following the Read Identifier Codes/OTP command, read operations access manufacturer code, device code, block lock
5. Block erase, full chip erase or (page buffer) program cannot be executed when the selected block is locked. Unlocked
6. Either 40H or 10H are recognized by the CUI (Command User Interface) as the program setup.
X=Any valid address within the device.
PA=Address within the selected partition.
