27. NAND Flash Memory Controller (FLCTL)
(2)
Continuous physical sectors can be read from or written to by specifying the start physical sector
address of NAND-type flash memory and the number of sectors to be transferred. Figure 27.10
shows an example of physical sector specification register and transfer count specification register
settings when transferring logical sectors 0 to 40, which are not contiguous because of an unusable
sector in NAND-type flash memory.
