8-Bit Merge Low and High
This option is used to merge two 8-bit data files into one 16-bit data file, allowing a
16-bit device to be programmed.
To merge two 8-bit files into one 16-bit file, follow this four step process:
1. Select the first 8-bit file, choose 8-Bit Merge Low, and load your file.
The 8-bit data will be loaded at all the even addresses (shown in bold below).
2. Select the second 8-bit file, choose 8-Bit Merge High, and load the file.
The 8-bit data will be loaded at all the odd addresses. (shown in italics below).
3. Program the 16-bit memory device.
4. Save the newly created 16-bit data file.

16-Bit Even and Odd
This option is used to split a 16-bit data file into two 8-bit data files.
To split a 16-bit data file into two 8-bit data files, follow this four step process:
1. Select the 16-bit data file that is to be split into two 8-bit files, select 16-Bit Even,
and load the file.
All the even data bytes will be loaded into the Optima Ram Buffer (as shown in
bold below).
2. Program the 8-bit memory device.
3. Repeat the file download operation, but select 16- Bit Odd.
All the odd data bytes will be loaded into the Optima Ram Buffer (shown in
italics below).
4. Program the second 8 bit memory device.

32-Bit Byte0…Byte3
This option is used to split a 32-bit data file into four 8-bit data files.
To split a 32-bit data file into four 8-bit data files, follow this eight-step process:
1. Select the 32-Bit data file that is to be split into four 8-bit files, select 32-Bit Byte
0, and load the file. Data bytes D0-D7 will be loaded into Optima Ram Buffer
(shown in bold).
2. Program the first 8-bit memory device.
3. Repeat the file download operation, and select 32-Bit Byte 1.
Data bytes D8-D15 will be loaded into the Ram Buffer (shown in italics).
4. Program the second 8-bit device.
5. Repeat the file download operation, and select 32-Bit Byte 2.
Data bytes D16-D23 will be loaded into the Ram Buffer (shown in underline).
6. Program the third 8-bit device.
7. Repeat the file download operation a forth time, and select 32-Bit Byte 3.
Data bytes D24-D31 will be loaded into the Ram Buffer (shown in regular).
8. Program the fourth 8-bit device.
