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 at Byte 4 starts DID and alternate with MID.
