I am using nRF52840 and SDK16 with S140 softdevice. How to generate an interrupt once 128 uS?

I want to use a timer to generate a Manchester data. The fastest data rate is 3.906 K-bit. So I want to generate a timer interrupt once 128 uS. Can anyone guide me how to generate it?

Thank you very much. I'll try it.
