3.4.2.14.6. The WR Flag

Setting the WR flag signifies that an MPU region write operation should be performed when a wrctl instruction is issued to the mpuacc register. Refer to the MPU Region Read and Write Operations section for more information. The WR flag always returns 0 when read by a rdctl instruction.
Note: Setting both the RD and WR flags to one results in undefined behavior.
