Unlocking

If your device has been locked by setting the MCU security status to "secure", and
mass erase via debug interface is not disabled, J-Link is able to unlock your Kinetis
K40/K60 device. The device can be unlocked by using the "unlock" command in J-
Link Commander.
For more information regarding the MCU security status of the Kinetis devices, please
refer to the user manual of your device.
