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.

F107h, default = 0000h

		FSA			NAND Flash Sector Address						00			00 (sector0), 01 (sector1),
														10 (Sector2) , 11 (sector3)

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.

F200h, default = 0000h

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).

Item	Description	BSC Value	Number of Sectors
		000 (Default)	8 sectors
		001	1 sectors
		010	2 sectors
BSC	Buffer Sector Count	011	3 sectors
(CASE1 : FSA=00)		100	4 sectors
		101	5 sectors
		110	6 sectors
		111	7 sectors
BSC		001	1 sectors
	Buffer Sector Count	010	2 sectors
(CASE2 : FSA=01)
		011	3 sectors
BSC	Buffer Sector Count	001	1 sectors
(CASE3 : FSA=10)		010	2 sectors
BSC	Buffer Sector Count	001	1 sectors
(CASE4 : FSA=11)

NOTE :

1)BSC is used only on load operation.

2)Operation not guaranteed for cases not defined in above table(CASE1, CASE2, CASE3,CASE4).
