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[6:0] are mapped to the internal A[17:11]
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
SA = 3C000h to 3FFFFh for Boot Block
SA = 3A000h to 3BFFFh for Parameter Block1
SA = 38000h to 39FFFh for Parameter Block2
SA = 30000h to 37FFFh for Main Memory Block1
SA = 2XXXXh for Main Memory Block2
SA = 1XXXXh for Main Memory Block3
SA = 0XXXXh for Main Memory Block4
