4.3 QSPI Flash Content
The module is fully tested in production but shipped with empty flash content (all 0xFFs) so the user
needs to program the modules in production. For development or production purposes the user
needs to download the Software Development Kit, which can be accessed via the customer support
portal. Registration is required and is possible via "https://support.dialog-
