caution

For some Nordic security chips, configuring the SDSC plugin content may be mandatory rather than optional. Please refer to the Nordic official documentation for details. PowerWriter will support the original Nordic files.

PowerWriter® supports manufacturer-specific functions through the use of plugin mode. It can support any specific functions requested by any manufacturer. The entry method is the same as that of other brands. After selecting the chip, if a plugin support icon appears on the rightmost side of the toolbar, the selected chip has the plugin support function, as shown below:

3：Notics​

The SDSC plugin function can only be used offline and cannot be operated online. When online debugging is required, offline programming needs to be executed first, the data needs to be pre-written, and then the operation can be carried out.
