Choose to erase all memory before programming, or to merge code.
| Erase All Before Program | Check to erase all memory before programming begins. Unless programming new or already erased devices, it is important to have this box checked. If it is not checked, the device is not erased and program code will be merged with the code already in the device. |
| Do not erase auxiliary memory | For devices that support auxiliary memory: Check to not erase aux memory when programming. Uncheck to erase aux memory when programming. |
