Hallo everyone. I'm working with the processor nRF51422 with S210 softdevice and I would like to use the HFCLK crystal oscillator for clocking another external periferal, only during the on-mode period of the system to reduce the overall power consumption. So my question is that it's possible to routing the signal "HCLK" or "PCLK16M" (16MHz) or at least "HCLK/2" (8MHz) into a General-purpose I/O pin (GPIO). Thank you.
