Unlocking LM3Sxxx devices

If your device has been "locked" accidentially (e.g. by bad application code in flash
which mis-configures the PLL) and J-Link can not identify it anymore, there is a spe-
cial unlock sequence which erases the flash memory of the device, even if it can not
be identified. This unlock sequence can be send to the target, by using the "unlock"
comnmand in J-Link Commander.
