9.1.2.4 Memory Write Protection
All the memory blocks have corresponding write protection bits (WRTAPP, WRTB and WRTC). If
write-protected locations are written from NVMCON registers, the memory is
not changed and the WRERR bit of the NVMCON1 register is set as explained in the “WRERR Bit” section in the “NVM - Nonvolatile Memory Control”
chapter.
