STEVAL-ID008V2 evaluation board, BlueNRG-2, DTM project, Low Frequency Clock selection

[RAlma.1]

Hi, 

I am experimenting with STEVAL-ID008V2 evaluation board and the DTM project from the SDK. It seems the DTM firmware using the external 32KHz clock for as the Low frequency clock source. Where about the source code of the DTM project I could set the low frequency clock source to use the internal RC only, as on my custom board I don't have a 32KHz external clock. Is it where I have pointed in the screenshot?

Many thanks,
