C, Issue Date: 2006/12/25 In the case of multi-byte commands of Page Program (PP), and Release from Deep Power Down (RES ) minimum number of bytes specified has to be given, without which, the command will be ignored. In the case of Page Program, if the number of byte after the command is less than 4 (at least 1 data byte), it will be ignored too. In the case of SE, exact 24-bit address is a must, any less or more will cause the command to be ignored. All attempts to access the memory array during a Write Status Register cycle, Program cycle or Erase cycle are ignored, and the internal Write Status Register cycle, Program cycle or Erase cycle continues unaffected.

Data bytes are shifted with Most Significant Bit first. Byte fields with data in parenthesis “( )” indicate data being read from the device on the DO pin. 2. The Status Register contents will repeat continuously until CS# terminate the instruction. 3. All sectors may use any address within the sector. 4. The Device ID will repeat continuously until CS# terminate the instruction. 5. The Manufacturer ID and Device ID bytes will repeat continuously until CS# terminate the instruction. 00h on Byte 4 starts with MID and alternate with DID, 01h on Byte 4 starts with DID and alternate with MID.
