------------------------------------------------------------------

This program executes tests for 1M Flash ROM. The basic controls 

are as follows:



	Control Pad Up/Down	: Select command

	A Button		: Execute command

	C Button Unit		: Change each parameter



The following are the definition of each command:

	FLASH CHANGE	:	Switches the Flash being used. Can

				specify from 0 to 3.

	READ ID		:	Read Flash ID.

	READ STATUS	:	Read the status of Flash.

	CLEAR STATUS	:	Clear the status of Flash.

	ALL ERASE	:	Deletes all the data of Flash.

	SECTOR ERASE	:	Deletes a specific sector of 

				Flash. The sector to be deleted is

				a sector which contains the page

				specified by page number.

	READ ARRAY(DMA)	:	Reads the specified page of Flash

				with DMA. The page to be read is

				the page length from the page

				specified by page number.

	WRITE BUFFER	:	Writes Flash buffer.

	WRITE ARRAY	:	Writes each page of Flash from

				Flash buffer. The page to be read

				is the page specified by page

				number.

	FILL WRITE DATA	:	Creates the write data pattern of

				a page length (1 PAGE)for the page

				specified by page number. Page

				numbers are inserted in the last 4

				bytes of the data.

	CLEAR ALL	:	Deletes the data in the read

	READ DATA		buffer of the test program.

	CLEAR ALL	:	Deletes the data in the write

				buffer of the test WRITE DATA

				program.

	ALL ERASE &	:	Deletes, creates write data and

	FILL & WRITE		writes the entire area of Flash.

	ALL READ	:	Reads data from the entire area of

				Flash. Data is read per page.

	ALL COMPARE	:	Compares the entire content of

				read buffer and the write buffer

				of the test program.

	REGION COMPARE	:	Compares the content of the

				specified area of the read buffer

				and the write buffer of the test

				program.  The area to be compared

				is the page length from the page

				specified by page number.

	ALL TEST	:	Executes ALL ERASE -> ALL FILL ->

				ALL WRITE -> ALL COMPARE as many

				times as specified.

	PAGE LENGTH	:	Specifies page length.  Other than

				motion experiment, specify 1 in
