Note: The internal address A[18:0] are converted from external Column/Row addres
Column/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].
SA = Sector Address, Please ref. to the "Table of Command Definition"
