Programing the DA14680 JTAG

Good day,
Consider the following scenario:
The minimal connections are made according to the hardware app-notes you posted. So there is a DA 14680 SoC on a PCB with components. How can this device now be programed?
How can the program files developed, using your software packages and development kits, be loaded onto the PCB for the programming of the PCB?
Can this be done using the JTAG ports of the DA14680?
