10.3.1 NVM User Row Mapping
The first two 32-bit words of the NVM User Row contain calibration data that are automatically read at device power on.
The NVM User Row can be read at address 0x804000.
To write the NVM User Row refer to NVMCTRL – Non-Volatile Memory Controller.
When writing to the user row the values do not get loaded by the other modules on the device until a device reset occurs.
