Hi,

You can find a simple description in chapter 3.3 on how to for instance enable DTM mode:
http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.appnotes/dita/appnotes/pdflinks/nan_34.html?cp=10_3

A typical sequence can be.

1. The application want to enter DTM mode (for instance a pin is pulled low or a command is received over BLE)
2. The application write a magic word to the GPREGRET register and execute a soft reset (NVIC_SystemReset()).
4. On reset, check if RESETREAS register is from soft reset.
5. If reset from soft reset then check GPREGRET value, else execute application.
6. If GREGRET value equal magic word then execute DTM, else execute application.

There is no need to write to flash or use FDS.

Best regards,
Kenneth
