about NRF_POWER->GPREGRET region

Dear Nordic.

Is NRF_POWER->GPREGRET register writing in NVMC?

FICR and UICR is saved in flash memory(NVMC) as written by [nRF51_RM_v3.0.pdf].

But, GPREGRET register isn't saved in flash memory(NVMC). It's saved in RAM.

Is it correct?

Best and regards. Thank you.

Hi,

You can find some information about the GPREGRET register in this thread. In short, it is a register in RAM that will retain its value through a wakeup from system off mode.

Best regards,

Jørgen
