To read the data byte at any specific location, select the location in the editable window
and press the Read Byte button, it reads the selected location data from the sensor

To write a single byte at a specific location, change the byte value and press the Enter
button on the computer. Then press Write Byte to write the data in the EEPROM.

To write all the 256 bytes of EEPROM, press the Write All button in the GUI. This writes
the bytes as seen in the editable box. To change the bytes at the memory location, type
the new value at that memory location and press Enter. To modify another memory
location, go to that location, type the bytes and then press Enter.

After all values are changed according to requirements, press Write All to program the
values in the EEPROM.

Fill Buffer is used to fill the area of EEPROM with the same data byte. Type the memory
location from where the data is to be written and also the destination memory location
address. Then enter the data byte in the Fill With area. Pressing the Fill Buffer button
programs the EEPROM selected area with selected data byte. This data byte can be
seen in the GUI by pressing the Read All button.

Copy Block is used to copy the data from memory location 0x00-0x7F to the location
0x80-0xFF. Therefore both upper and lower 1 Kbit data is similar after the Copy Block
command.
