that data. If even one bit in the buffer were to change, this value would be different. It is
worth noting down the checksum value for a specific data file or from a master IC which has

6. In this example we need to set the protection on this IC. Because this IC has several

protection options we need to click on the button to enter the "Device
Option'\'Lock Bit Option" page and select the required protection options. Press the
button to save the selection and return to the main screen.
If you do not carry out this process the programmer will not correctly protect the IC and will
cause a error.
