S3C2440X RISC MICROPROCESSOR

NAND FLASH CONTROLLER

6-5

SOFTWARE MODE

S3C2440X only supports software mode access. Using this mode, you can completely access the NAND flash

memory. The NAND Flash Controller supports direct access interface with the NAND flash memory.

1) Writing to the command register = the NAND Flash Memory command cycle

2) Writing to the address register = the NAND Flash Memory address cycle

3) Writing to the data register = write data to the NAND Flash Memory (write cycle)

4) Reading from the data register = read data from the NAND Flash Memory (read cycle)

5) Reading main ECC registers and Spare ECC registers = read data from the NAND Flash Memory

NOTE : In the software mode, you have to check the RnB status input pin by using polling or interrupt.
