Notes:
1. The cycle means the write command cycle not the FWH clock cycle.
2. The Column Address / Row Address are mapped to the Low / High order Internal Address. i.e. Column Address
A[10:0] are mapped to the internal A[10:0], Row Address A[7:0] are mapped to the internal A[18:11]
3. Address Format: A14−A0 (Hex); Data Format: DQ7-DQ0 (Hex)
4. Either one of the two Product ID Exit commands can be used.
5. SA: Sector Address
