Memory Address Protection disable

[vonh2]

Hi, I noticed that in the manual:
"Write 0 to EFM_PROTn is valid but write 1 to EFM_PROTn will not be effective.
There are 2 ways to configure EFM_PROTn:
• Write data to EFM_PROTn registers
• Program data to 0x10000A04 and 0x10000A08 will set initial values for EFM_PROTn (effective after
reset)."

what data should I program to the 0x10000A04 and 0x10000A08 to reset the values for EFM_PROTn? For my case, I need to disable the address protection when need.

Thank you

Cannot directly assignment by means of pointers dueto in flash array.
You may use the flash operation, such as FLASH_DRV_EraseSector.

The address of 0x10000A04 is in CUS NVR.
If it is necessary to restore the default values (Disable the address protection), it is sufficient to erase the CUS NVR (restored to: 0xFFFFFFFF).
note If there is other data in the CUS NVR before (e.g. flag of Disable JTAG) it is necessary to consider whether the previous data should be reprogrammed.

run Thanks for the information,

Is it enough if I used a pointer to 0x10000A04 and 0x10000A08 and set value for ADDR_PROT0/1?
