FPA
(NAND Flash Page Address): NAND Flash start page address in a block for page read or cache program 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) = 00
FSA range : 00~11, 2bits for 4 sectors

7.16 Start Buffer Register (R/W): F200h, default=0000h
BSC
(BufferRAM Sector Count): this field specifies the number of sectors to be read or programmed or copy back programmed.
Its maximum count is 4 sectors at 00(default value)value. For a single sector access, it should be programmed as value 01.
However internal RAM buffer reached to 11vaule(max value), it count up to 00 value to satisfy BSC value.
For example1) If BSA=1010, BSC=11, then selected BufferRAM are ’1010 ->1011 ->1000’
There is restriction in BootRAM case.
For example2) If BSA=0000, BSC should be 01 or 10.
If BSA=0001, BSC should be 01.
BSA
(BufferRAM Sector Address): It is the place where data is placed and specifies the sector 0~3 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[1:0] are the selection bits for sectors in a BufferRAM
While one of BootRAM or DataRAM0 interfaces with memory, the other RAM is inaccessible.
