accessing the NDFDTR0 register. When you write to this register, the data is written to the
NAND Flash. When you read from this register, the data is read from the NAND Flash.
The NDFDTR0 register is used for both channel 0 and channel 1.
example, 4 bytes of data can be transferred from 32-bit internal RAM to 8-bit NAND Flash
memory by DMA operation by setting the destination address as NDFDTR0. (NDFDTR1
cannot be set as the destination address.) The actual DMA operation is performed by first
reading 4 bytes from the internal RAM and then writing 1 byte to the NAND Flash four
times from the lowest address.
details, see Table3.11.3.
Write and read operations to and from the NAND Flash memory are performed by
A total of 4 bytes are provided as data registers to enable 4-byte DMA transfer. For
To access data in the NAND Flash, be sure to access NDFDTR0 (at address 1FF0). For
operations are performed in different manners, it is not possible to read out the data that has been just written.
