5.1.2 Separate File Data for Programming
By using the File Mode selection in the File Type dialog box, you can select the data
of a file and write it to several chips of the same type. This allows you to load the file
several times according to your needs. There are three methods for separating the
file data:
•
Based on byte (8bit), divide the file into two parts by the odd and even
address. Program the two parts into two chips respectively. When loading the
file, select Even as the File Mode to write the data in the addresses 0,2,4,6, etc.
to one chip. Select Odd as the File mode to write the data at the address
1,3,5,7, etc. to the other chip.
•
Based on the byte (8-bit), divide the file into four parts by address of the first
byte, the second byte, the third byte and the fourth byte out of every four
bytes. Program the four parts to four chips respectively. When loading the
file, select the 1st byte of 4 as the File Mode to write the data in the addresses
0, 4, 8, 12 (or C if HEX), etc. to one chip. Then select 2nd byte of 4, 3rd byte of
4, and finally 4th byte of 4 to write the remaining data to the other three chips.
•
Based on the word (16-bit), divide the file into two parts by address of the
first two bytes and the last two bytes out of every four bytes. Program the
two parts to two chips respectively. When loading the file, select the 1st two
bytes of 4 as the File Mode to write the data in the addresses 0, 1, 5, 6, etc. to
one chip. Then select 2nd two bytes of 4 to write the remaining data to the
other chip.
5.1.3 Program Two or More Files to One Chip
User can load several files into the buffer and write them to the chip. The following
explanation gives an example of programming three files (Sample1, Sample2, and
Sample3) to one chip. The example assumes the following:
•
Write the data from the address 200 (Hex) of the file Sample1 to the address 0
of the chip.
•
Write the data from the address 0 (Hex) of the file Sample2 to the address 3000
