Non Volatile Memory (NVM) User Row (UROW)

Description

The Non Volatile Memory (NVM) User Row (UROW) contains device configuration data that are automatically read at device power-on. This row can be updated using the NVMCTRL peripheral. The Device Programming tool (included with the Atmel Studio 7 IDE) offers a graphical user interface, easing the modification of UROW. When writing to the NVM UROW, the new values are not loaded by the other peripherals on the device until a device reset occurs.

The NVM UROW can be read at address 0x00804000. SAM L10 and SAM L11 have different NVM UROW mappings.

​

Refer to the product data sheet to view the UROW Bitfield Definitions for SAM L10 and SAM L11.
