Device specifics
10.10.1 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 special 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.
