27. NAND Flash Memory Controller (FLCTL)
27.4.3
In sector access mode, flash memory can be read from or written to in sector units by specifying
the number of physical sectors to be accessed.
Since 512-byte data is stored in FLDTFIFO and 16-byte control code is stored in FLECFIFO,
DMA transfer can be performed by setting the DREQ1EN and DREQ0EN bits in FLINTDMACR.
Figure 27.8 shows the relationship of DMA transfer between sectors in flash memory (data and
control code) and memory in the address space.
