Flash

Readme
 
This is a C language project that demonstrates writing to internal flash on the MSPM0. The data sheet specifies the flash is indeterminate after erasing, and only determinate after it has been programmed. However, experimentation shows the value after erase is 0xFF. After erasure, flash can only be programmed once. To change a flash value, one must erase the sector and program it again.
 
Derived from Texas Instrument code
