NVM Software Calibration Area Mapping

The NVM Software Calibration Area contains calibration data that are determined and written during production test. These calibration values should be read by the application software and written back to the corresponding register.

The NVM Software Calibration Area can be read at address 0x00806020.

The NVM Software Calibration Area can not be written.
