Internal Flash

Supported Regions

The internal flash is divided into two different regions: Program flash and FlexNVM.

Flash bank Size (KiB) Memory region
Program flash 1536 0x00000000 - 0x0017FFFF
FlexNVM 512 0x10000000 - 0x1007FFFF
The program flash memory contains a 16-byte flash configuration field at address 0x400 that stores default protection settings and security information that allows the MCU to restrict access to the FTFM module. 

The register portion of the flash configuration field is loaded into associated flash registers during the reset sequence.
