+ *
+ * MSP430 code examples are self-contained low-level programs that typically
+ * demonstrate a single peripheral function or device feature in a highly
+ * concise manner. For this the code may rely on the device's power-on default
+ * register values and settings such as the clock configuration and care must
+ * be taken when combining code from several examples to avoid potential side
+ * effects. Also see www.ti.com/grace for a GUI- and www.ti.com/msp430ware
+ * for an API functional library-approach to peripheral configuration.

+//  MSP430F20xx Demo - Flash In-System Programming, Copy SegC to SegD
+//
+//  Description: This program first erases flash seg C, then it increments all
+//  values in seg C, then it erases seg D, then copies seg C to seg D.
+//  Assumed MCLK 771kHz - 1428kHz.
+//  //* Set Breakpoint on NOP in the Mainloop to avoid Stressing Flash *//
