1 (CHANGE): The data in sectors of the non-linearly mapped area can be changed (erased or written)
EN_PRG_LIN

NVM protection of data in linear sectors

0 (NO_CHANGE): The data in sectors of the linearly mapped area can not be changed

1 (CHANGE): The data in sectors of the linearly mapped area can be changed (erased or written)
EN_PRG_CBSL

NVM protection of data in CBSL region

0 (NO_CHANGE): The data in region defined by NVMBSL can not be changed

1 (CHANGE): The data in region defined by NVMBSL can be changed (erased or written)
EN_RD_NL

NVM read protection of data in non-linear sectors

DIS_RDUS

Configuration of NVM read protection for sector 1…n with EN_RD_* = 0

0 (NVM_READ_UNSAVE): Only active when nvm_read_unsafe_i = 1 and not for nvm_read_unsafe_i = 0

1 (INDEPENTENT): Independent from nvm_read_unsafe_i; also write accesses to sector 1…n are prevented
