NVM User Row (UROW)

The Non Volatile Memory User Row (UROW) contains device configuration data that are automatically read at device power-on.

This row can be updated using the NVMCTRL peripheral.

When writing to the NVM User Row, the new values are not loaded by the other peripherals on the device until a device reset occurs.

The NVM User Row can be read at the address 0x00804000.

SAM L10 and SAM L11 have different NVM User Row mappings.
