TASKS_CONSTLAT is not working on NRF54L15

[gandyhuang]

HI,

I am using "NRF_POWER->TASKS_CONSTLAT = 1;" to enable CONSTLAT, but when i  printf("TASKS_CONSTLAT %d",NRF_POWER->CONSTLATSTAT); the result is still 0; how can i  config it? thanks

For Cross power-domain use, please refer to the SDK documentation here: https://docs.nordicsemi.com/bundle/ncs-3.2.4/page/nrf/app_dev/device_guides/nrf54l/pinmap.html. Keep in mind that the sleep current increases while constant latency is enabled (typ. from 3 ua to 500ua).
