Note: In order to secure the iNVM memory (such as avoiding any further write to it after
manufacturing), a word auto-load structure must be present in iNVM for setting the iNVM bit
to 1b in word address 0x0A.
3.4.2.2 CSR Auto-load Structure
The CSR auto-load structure is defined as follows:
MSB[15] ..............................................................................................................LSB[0]
