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
HI,
Hi Gandy
Okay, so we found something with some further testing on our end. There seems to be a bad register definition in the nrf54l15_application.svd file, so it reads the wrong register when you write out the POWER_CONSTLATSTAT register value.
Reading the memory from the register location in the nRF54L15 datasheet should return the correct value, and constant latency mode should be running correctly. You should be able to see that from the power consumption for example.
For reference, here's a snippet of where the register address is specified in the datasheet (page 98):
Best regards,
Simon
