    FPA
    (NAND Flash Page Address): NAND Flash start page address in a block for page read or copy back program or program operation.
    FPA(default value)=000000
    FPA range: 000000~111111 , 6bits for 64 pages
    FSA
    (Flash Sector Address): NAND Flash start sector address in a page for read or copy back program or program operation.
    FSA(default value) = 0
    FSA range : 0~1, 1bits for 2 sectors

    BSC
    (BufferRAM Sector Count): this field specifies the number of sectors to be read or programmed or copy back programmed.
    Its maximum count is 2 sectors at 0(default value)value.
    For a single sector access, it should be programmed as value 1 and it should be programmed as value 0 for two sectors.
    However internal RAM buffer reached to 1 value(max. value), it counts up to 0 value to satisfy BSC value.
    for example) if BSA=1101, BSC=0, then selected BufferRAM are ’1101->1100’.
    BSA
    (BufferRAM Sector Address): It is the place where data is placed and specifies the sector 0~1 in the internal BootRAM and DataRAM.
    BSA[3] is the selection bit between BootRAM and DataRAM.
    BSA[2] is the selection bit between DataRAM0 and DataRAM1.
    BSA[0] is the selection bit between Sector0 and Sector1 in the internal BootRAM and DataRAM.
    While one of BootRAM or DataRAM0 interfaces with memory, the other RAM is inaccessible.
