Page write operation
Page write operation is described below. Only lower 4 bits of address are valid. Upper 4 bits are fixed
as “1111”. Therefore the address which is written after “1111 1111” becomes “1111 1110”.

Current address read
Current address read operation is described below. The data that is read by this operation is obtained
as “last accessed address + 1”. Therefore, It is consequent to return “1111 1110” after accessing the
address “1111 1111”.
