In latest nrfx versions the support for RTCx for nRF54L15 has been
removed and the GRTC should be used instead.
The GRTC SYSCOUNTER has a resolution of 1us, so then optimal cputime freq
would be equal to 31250Hz to ensure smooth calculations, but since the LL
timing is tuned for 32768Hz, let's simulate the 32768Hz for now.
@mkasenberg mkasenberg force-pushed the nrf54l15-grtc-as-cputimer branch from 5194dd9 to 6b37cdc Compare May 15, 2026 15:37
