-// Flash Security Setting. On Teensy 3.2, you can lock the MK20 chip to prevent
-// anyone from reading your code.  You CAN still reprogram your Teensy while
-// security is set, but the bootloader will be unable to respond to auto-reboot
-// requests from Arduino. Pressing the program button will cause a full chip
-// erase to gain access, because the bootloader chip is locked out.  Normally,
-// erase occurs when uploading begins, so if you press the Program button
-// accidentally, simply power cycling will run your program again.  When
-// security is locked, any Program button press causes immediate full erase.
-// Special care must be used with the Program button, because it must be made
-// accessible to initiate reprogramming, but it must not be accidentally
-// pressed when Teensy Loader is not being used to reprogram.  To set lock the
-// security change this to 0xDC.  Teensy 3.0 and 3.1 do not support security
-// lock.
