Section 22 AND/NAND Flash Memory Controller (FLCTL)
(2)
Continuous physical sectors can be read or written by specifying the start physical sector of
NAND-type flash memory and the number of sectors to be transferred. Figure 22.16 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.
22.4.6
The FLCTL generates and adds an ECC code during write operation in sector access mode and
performs ECC error check during read operation in sector access mode. The FLCTL, however,
does not perform error correction. Note that errors must be corrected by software.
