Hi all,
I have some trouble with the WRITE_PROTECT register. I want to lock the PMIC so the WRITE_PROTECT [10h] register should has the value 0x40.
If i write this to the register and read it back everything is fine but if I do a power cycle the register value is 0x00 again.
As I can see in the in the datasheet this register is not in NVM but is it possible that the register has value 0x40 after power cycle?
Thanks,
Maximilian
