Hi,

Set P1.08 PIN_CNF CTRLSEL register to GRTC

Hi,

Based on the above reference, I called nrfy_grtc_clkout_set(NRF_GRTC, NRF_GRTC_CLKOUT_FAST, true) in main and did not see that p1.08 has 16M clock output

Hi ,

Thank you for your support. I tested and I can see the 32.768k clock output normally. But I have to add that since p0.04 and p1.08 are temporarily used by button2/3, I need to add an .overlay file to delete the button2/3 node, as follows:

/ {

	aliases {
		/delete-property/ sw2;
		/delete-property/ sw3;
	};
};
/delete-node/ &button2;
/delete-node/ &button3;

I am still verifying whether 16M is feasible.

Hi!

Snippet:

#include <haly/nrfy_grtc.h>
 
 
int main(void)
{
 
    nrfy_grtc_clkout_set(NRF_GRTC, NRF_GRTC_CLKOUT_32K, true);
