This file contains a summary of the files required for a NAND Flash test application.

NAND_IO_Test.c:
	This file contains source code which provides a real implementation of the 
	NAND_IO drivers.  The NAND IO drivers include an implementation of all the 
	data sheet commands for a Micron NAND device including Reset, Read ID, Page Read,
	Page Program, Cache Program, Cache Read, etc.  For additonal details see 
	descriptions below.
	The source code also shows how to check a Micron NAND flash
	device for bad blocks, how to create a simple bad block table based on the 
	results of the bad block check, and how to skip operations on bad blocks based on
	the bad block table.

	Reset
		- Issue reset command (0xFF) to NAND device
	Read ID
		- Issue Read ID command and display Read ID bytes 0, 1, 2, 3
	Read Unique ID
		- Issue Read Unique ID command and display Unique ID bytes 0 - 15.
	Read for bad blocks.
		- This test provides an example for setting up a simple bad block table.
			Read byte 2048 of page 0 and page 1 of each block. If either of these
			bytes is non-FF add block to bad block table.
	Erase all good blocks.
		- Issue erase command to all good blocks and check Pass/Fail status.
	Page Program quick test
		- Program Block 0, page 2 with 0xAA data in all bytes.
		- Program Block 0, page 3 with 0x55 data in all bytes.
	Page Read quick test
		- Read Block 0, page 2 and check for 0xAA data in all bytes.
		- Read Block 0, page 3 and check for 0x55 data in all bytes.
	Random Data Program
		- Program 0x00 to block 0, page 4 bytes 0 - 511 and 2048 - 2063.
		- Program 0x01 to block 0, page 4 bytes 512 - 1023 and 2064 - 2079.
		- Program 0x02 to block 0, page 4 bytes 1024 - 1535 and 2080 - 2095.
		- Program 0x03 to block 0, page 4 bytes 1536 - 2047 and 2096 - 2111.
	Random Data Read
		- Read for 0x00 in page 4 bytes 0 - 511 and 2048 - 2063.
		- Read for 0x01 in page 4 bytes 512 - 1023 and 2064 - 2079.
		- Read for 0x02 in page 4 bytes 1024 - 1535 and 2080 - 2095.
		- Read for 0x03 in page 4 bytes 1536 - 2047 and 2096 - 2111.
	Cache Program
		- Program 0x55 data to Block 0, Page 5 - 10 all bytes.
	Cache Read
		- Read for 0x55 data in Block 0, Page 5 - 10 all bytes.
	Internal Data Move
		- Copy Block 0 page 5 - 10 to pages 11 - 16 respectively.
		- Read back data in pages 11 - 16 to confirm success.
	Internal Data Move with Random Data Input
		- Copy Block 0, page 4 to block 0 page 17 and change bytes
			512 - 1023 and bytes 2064 - 2090 to 0x00.
	Page Program long test 
		- For each good block program 0xAA in even pages and 0x55 in odd pages.
	Page Read long test
		- For each good block read for 0xAA in even pages and 0x55 in odd pages.
	Erase all good blocks
	Page Read, all 0xFF
		- Check all bytes of all pages of all good blocks for 0xFF data


NAND_IO.c
	This file contains source code for the NAND I/O drivers, which represent the 
	standard command set for Micron NAND flash devices.

NAND_IO.h
	Header file.


NAND_LLD.h
	This is the NAND Low Level Driver Header file.  THIS FILE MUST BE MODIFIED 
	BEFORE THE NAND_IO DRIVERS CAN BE RUN ON A SPECIFIC SYSTEM.  At a minimum
	the address Offsets for CLE, ALE, RE, and WE must be changed.  Other changes 
	may also be required depending on the hardware of the specific system.
