Operation Description
registers. It also contains the ECC calculating circuits. Please see 3.17.3.2 for details
of the ECC. This section explains the operations for accessing the NAND Flash.
read cycle for ND0FDTR is completed after the external read cycle for the
NAND-Flash is finished. Likewise, the write cycle for ND0FDTR is completed after
the external write cycle for the NAND-Flash is finished.
