I have a question about memory on the MK50DN512CMC10. Does this device contain any non-volatile storage,
that can be used by the program (running out of program flash) to store a few hundred bytes of data, for example unique serial numbers and configuration information? I am a bit confused by the documentation. In the K50 Sub-Family Reference Manual, there is a table on page 99 (Section 188.8.131.52) that shows 4KB of FlexRAM in this device, but it has no FlexNVM. What storage resources are actually available?
