NVM flash read write

This example application demonstrates how to use the NVM to erase and program the internal Flash memory.

Description

This example uses the NVM peripheral library to erase a page and write an array of values to the internal Flash memory. It verifies the value written by reading the values back and comparing it to the value written.
