3.17 NAND-Flash Controller

Characteristics

The NAND-Flash controller (NDFC) is provided with dedicated pins for connecting with

NAND-Flash memory. The NDFC also has an ECC calculation function for error correction.

Although the NDFC has two channels (channel 0, channel 1), all pins except for Chip

Enable are shared between the two channels. Only the operation of channel 0 is explained

The NDFC has the following features:

1) Controlled NAND-Flash interface by setting registers.

2) ECC calculating circuits. (for SCL-type)

external circuit.

Note 2: The two channels cannot be accessed simultaneously. It is necessary to switch between the two channels.

(Write Protect) pin of NAND Flash is not supported. If this function is needed, prepare it on an
