4E4th-IDE - the Integrated Development Environment for your MSP430 LaunchPad ... Saving your Program
Due to the circumstance that FLASH memory is only erasable block wise, there are certain problems with interactive programming.
That means, a program has to be saved when finished programming and before switching off power, simply by typing SAVE.
For the ease of use there is an Autosave function installed, which is always set after START, but may be switched off.
This Autosave function writes SAVE automatically to the LaunchPad target after each download and when closing the connection to the target by clicking on STOP, in case a SAVE hasn't been done by the user. In this case a pop up shows up, asking for saving.
