2.8.16 Start Address8 Register F107h (R/W)
This Read/Write register describes the NAND Flash start page address in a block for a page load, program operation and the NAND Flash
start sector address in a page for a load, or program operation.

NOTE :
1) Only 6bits must be used for 64pages in SLC area. (SLC:64pages, MLC:128pages)
2) Sectors 4-7 in a page are not directly addessable using FSA. However, they can be accessed using BSA and BSC (See Below).FSA must be 00
in program operation.
2.8.17 Start Buffer Register F200h (R/W)
This Buffer Sector Count(BSC) specifies the number of sectors to be loaded.

The BufferRAM Sector Address (BSA) is the sector 0~3 address in the internal BootRAM and DataRAM where data is placed.
NOTE :
1) In case of 'Program' and 'Load', Internally BSA fix first sector of DataRAM0(BSA=1000).
