Can DTM on nRF52840 be controlled by SPI interface?

[JPierpont]

We currently have a SPI interface between MSP and the Nordic nRF52840. In the DTM documentation it indicates UART is used to command the tests. Is it possible to do this using SPI?j

Theoretically yes, it's just not defined and not implemented in any example. But surely if you have some upper tester which will know how to run DTM commands over SPI instead UART then you can modify DTM FW examples from nRF5 SDK to communicate over SPI.
